IDE hangs on startup, with no error shown in logs

Wark · December 5, 2023, 6:23am

Hi,

I'm also encountering an issue with the arduino IDE. I have tried many solutions on the forum, such as the complete clean reinstall using third party tools to make sure the registry is clean for example, but nothing seems to work... I would greatly appreciate some help!

I'm running Arduino IDE 2.2.1 on windows 10, and I get the following on powershell:

PS C:\Program Files\Arduino IDE> & ".\Arduino IDE"

Hi @Wark

Please provide a detailed description of the problem you are encountering. Make sure to include the full and exact text of any error or warning messages you might have encountered.

Everything looks normal.

Wark · December 7, 2023, 1:27pm

Excuse me if my last message wasn't clear. I have the same issue, as in it's stuck on the loading screen, for ever.

I'm even more confused now that you told me that everything looks normal on the powershell...

What could the problem come from?
Thank you for your help. In the meantime i reverted to the old arduino IDE to code...

ptillisch · December 8, 2023, 6:46am

Thanks for the clarification. 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 Arduino IDE 2.x to functionality by deleting the folders where the data is stored. This will force Arduino IDE 2.x 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.

Hi,
I've deleted the aforementioned folders, but the app still hangs on startup...
(Sorry for the delay, I didn't received an email notification because of the topic split).

I have the same log on powershell as earlier before & after deleting the folders

Hi,
Do you have any hints of what i could change? despite my numerous tries, it's still not working...
thank you very much!
