IDE hangs on startup, with no error shown in logs

mtmr · February 14, 2024, 5:57am

Hello!
I installed Arduino IDE, but it doesn't start and stays at the startup screen.

First, I connected the arduino to my computer via USB. The ON lamp on the Arduino is lit. The L lamp is blinking. In this situation, when I start the Arduino IDE on my computer, a startup screen with the Arduino logo repeatedly getting bigger and smaller is displayed, but it doesn't start.

This is my first time installing Arduino IDE.
I have installed it in a windows virtual environment inside my chromebook and am performing operations within the virtual environment.
W10-D-CL01-1321
Arduino IDE 2.3.0
The computer is connected to the Internet.
I downloaded the Arduino IDE for Windows Win 10 and newer, 64 bits.

I performed the operation using PowerShell using the URL below as a reference.

Then, I got the following text. Please help, anyone?

Hi @mtmr.

Did the problem of the IDE startup hanging at that pulsing Arduino logo animation phase happen during the session that produced that text?

I ask because I looked at the logs and I don't see any indication that something went wrong while they were being produced.

mtmr · February 14, 2024, 7:02am

Thank you for your reply!
When Powershell wrote this texts, the Arduino IDE only made the logo bigger and smaller, but did not start.
Other than this time, this situation happens every time I try to start the Arduino IDE.

ptillisch · February 14, 2024, 7:18am

It is possible the problem is caused by some problem in the Arduino IDE application configuration data. If so, it should be possible to restore the IDE to functionality by deleting the folders where the data is stored. This will force Arduino IDE to automatically regenerate the default configuration data.

Please try this:

The folders to be deleted do not contain any of the data for your sketch projects so deleting them should not result in the loss of any irreplaceable data. However, please always be careful when deleting things from your computer. When in doubt, back up!

Close all Arduino IDE windows if the IDE is already running.
Delete the folder at the following path:
```
C:\Users\<username>\.arduinoIDE\
```
(where <username> is your Windows username)
Delete the folder at the following path:
```
C:\Users\<username>\AppData\Roaming\arduino-ide\
```
(where <username> is your Windows username)
If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".

Now start Arduino IDE again. Hopefully this time it will start up fully.

The Arduino IDE preferences will have been reset to their default values. If you had previously made any customizations to the preferences (e.g., the "Additional Boards Manager URLs" preference) then you will now want to reconfigure the IDE as necessary.

Please let me know if you have any questions or problems while following those instructions.

mtmr · February 16, 2024, 7:00am

Thank you for answering!
I tried following your instructions, but the Arduino IDE only made the logo bigger and smaller, but did not start...
What should I do?

ptillisch · February 16, 2024, 9:20am

Arduino IDE automatically generates log files while it is running. I'm going to ask you to provide the latest log file from your computer. It might contain information that will help us to identify the problem.

Please do this:

Open a forum reply here by clicking the "Reply" button.
Click the "Upload" icon () on the post composer toolbar:

The "Open" dialog will open.
In the "Open" dialog, select the latest .log file from this folder (the files are named according to the date):
```
C:\Users\<username>\AppData\Roaming\Arduino IDE\
```
(where <username> is your Windows username)
ⓘ Note that the C:\Users\<username>\AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".
Click the "Open" button.
The dialog will close.
Click the "Reply" button to publish the post.

Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .log file onto the post composer field to attach it.

Please let me know if you have any questions or problems while following those instructions.

Hi,
I have started the ide using & ".\Arduino IDE". The IDE started and offered me an update to 2.3.1 which I installed. The IDE still does not start, I just see the pulsating Arduino icon and nothing more.
Using windows 10 on a corporate managed machine with limited authority

uod-james · February 16, 2024, 12:46pm

I just tried IDE with enhanced privileges (like run as admin) and it opens correctly.

uod-james · February 16, 2024, 1:05pm

I went back to the regular user, still not opening.
I deleted the folders suggested, same
Opened with elevated rights, and was offered library updates which I installed but some failed. My sketchbook location was not correct, fixed it, I then chose an Uno the was connected, not all the examples were present.
Went back to regular user, IDE started normally (!) was offered more library updates, installed them all, all examples were available and it seems to be working - I do not know which parts were relevant but mine is now working.

ptillisch · February 17, 2024, 7:40am

Congratulations on getting it working! Thank you for taking the time to post an update.

Regards,
Per

mtmr · February 19, 2024, 1:02am

Hello.
Thank you for your reply!
I tried your instructions, but I was unable to upload because the message "New users cannot attach files." was displayed.
I copied and pasted the contents of the file below.
Could you please check it?

On the first run after a fresh installation, Arduino IDE downloads some additional essential components from the Internet and installs them. If it can't install those components then the startup fails. So the computer must have access to the Internet on the first startup.

The errors indicate Arduino IDE is not able to access the Internet. If it is not already, please connect your computer to the Internet, close the Arduino IDE window, then start Arduino IDE again. This time it should start up successfully.

After that first run, an Internet connection is not required. However, there are some supplemental features such as "Library Manager" that have an inherent dependency on the Internet. Those features will not be usable while your computer is offline. But the essential functionality of editing, compiling, and uploading sketches will be available even without an Internet connection.

mtmr · February 19, 2024, 3:47am

Thank you for your reply.
With my computer connected to the Internet, I connected the Ardino to the computer via USB and started the Arduino IDE, but it did not start...
What should I do?

sterretje · February 19, 2024, 4:27am

Just a FYI, you do not have to connect your board to the computer to be able to use the IDE.

ptillisch · February 19, 2024, 5:07am

I'm sorry to hear that.

I'm going to ask you to post some additional information that might help us to identify the problem.

This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

Close all Arduino IDE windows if the IDE is already running.
Start Windows "File Explorer".
Open the Arduino IDE installation folder.
ⓘ The default installation location is at one of the following paths:
- ```
C:\Program Files\Arduino IDE
```
- ```
C:\Users\<username>\AppData\Local\Programs\Arduino IDE
```
  (where <username> is your Windows username)
  If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".
In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
From the context menu, click "Open PowerShell window here".
Windows PowerShell will now open with the current directory set to the Arduino IDE installation folder.
Type the following command:
```
& ".\Arduino IDE"
```
Press the Enter key.
Debug output should now be printed to the PowerShell window as Arduino IDE starts.
Wait until you are sure the IDE startup has gone into the hang state
(as indicated by no additional output being printed to the terminal).
Switch back to the PowerShell window if the Arduino IDE window took the focus.
Press the Ctrl+Shift+A keyboard shortcut.
This will select all the text in the PowerShell window.
Press the Ctrl+C keyboard shortcut.
This will copy the contents of the PowerShell window to the clipboard.
Open a forum reply here by clicking the "Reply" button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press the Ctrl+V keyboard shortcut.
This will paste the output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the "Reply" button to post the output.

Please let me know if you have any questions or problems while following those instructions.

mtmr · February 19, 2024, 6:05am

I did not know, thank you for letting me know!

mtmr · February 19, 2024, 6:14am

Hello. thank you for your reply.
I tried your instructions.
(Since it was not possible to select all using the shortcut key, I selected all by dragging and dropping the mouse cursor.)
Please check.
