Arduino 2.0.3 stuck on loading screen

I just downloaded Arduino again since my robotics class will be using it but whenever I try to open it, it would just show me the logo on a grayish screen. It doesn't even load at all after like 2 hours of me waiting.

Please help! I'm using my laptop running on Windows 11 and I haven't encountered this problem before when I first used Arduino. It could be the compatibility of the version I'm using but all my classmates' (they all using Windows 11 too) have theirs up and running smoothly.

Hi @aaaaaaa1646277272. I'm going to ask you to post some additional information that might help us to identify the problem.

Please do this:

  1. Start Windows "File Explorer".
  2. Open the Arduino IDE installation folder.
    (usually C:\Program Files\Arduino IDE or C:\Users\<username>\AppData\Local\Programs\Arduino IDE).
  3. In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
  4. 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.
  5. Type the following command:
    & ".\Arduino IDE"
    
  6. Press the Enter key.
    Debug output should now be printed to the PowerShell window as Arduino IDE starts.
  7. 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).
  8. Switch back to the PowerShell window if the Arduino IDE window took the focus.
  9. Right click on the title bar of the PowerShell window.
    This will open a context menu.
  10. Select Edit > Select All from the context menu.
    This will select all the text in the PowerShell window.
  11. Press Ctrl+C.
    This will copy the contents of the PowerShell window to the clipboard.
  12. Open a forum reply here by clicking the Reply button.
  13. Click the </> 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.
    Code block
  14. Press Ctrl+V.
    This will paste the output into the code block.
  15. Move the cursor outside of the code block markup before you add any additional text to your reply.
  16. Click the Reply button to post the output.

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

That's all I got. I also got a Windows Security Alert for mdns-discovery (I don't know if that should happen though)

Thanks. I see the problem here:

On the first run after a fresh installation, and when an update of them is available, Arduino IDE automatically download the serial-discovery and mdns-discovery tools from the Internet and installs them on your computer. These tools are required so if for some reason the IDE can no find the tools then it fails to start.

The problem is usually caused by the antivirus software quarantining the files after Arduino IDE installs them. So you have the folders where the files should have been, but the files are not in the folder (because they are in the quarantine).

Please check your antivirus software quarantine to see if you can restore the files. If you do that and then restart Arduino IDE, it should start up without a problem.

The files should be located at these paths:

C:\Users\jewel\AppData\Local\Arduino15\packages\builtin\tools\mdns-discovery\1.0.6\mdns-discovery.exe
C:\Users\jewel\AppData\Local\Arduino15\packages\builtin\tools\serial-discovery\1.3.3\serial-discovery.exe

As I mentioned above, Arduino IDE also automatically updates these tools whenever Arduino releases new versions of them. So you will also likely want to make the appropriate adjustments to your antivirus configuration so that it doesn't interfere with those updates.

Not sure what the application's name is (not behind a PC). Either there should not be a space or yoy must use ".\Arduino IDE" with the double quotes as shown in post #2.

Hi @DarrenHerbert. I see the problem here:

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.

Hi @rofiqvb. Are you experiencing some problem with Arduino IDE? The output you shared looks perfectly normal, without any indication that something is wrong.

A post was split to a new topic: May I know what is the problem here

thank you for the question and to the people who replied - I have windows 11 on my laptop and had the same issue.
resolved it by adding arduino ide to the applications that windows allows to communicate through its firewall
Go to "Firewall & Network Protection " then "Allow an app through firewall" then "Change Settings" therafter "Allow another app"
