IDE hangs on startup

Continuing the discussion from IDE hangs on startup:

I have the same issue. The "splash screen" does not close. Nothing happens when Im using the menus. sometimes there is a box with something behind the splash screen that i can close with enter.

Hi @needlegate. I think the thing to try for troubleshooting in this case will be to start the Arduino IDE 2.x from the command line. That will provide some output that might be useful in identifying the problem.

So if you can do that, please post the full output copied from the terminal in a reply here. It will probably be longer than the forum's 9000 character maximum limit. If so, save it to a text file and attach it to the reply. If you click the "Reply" button here, you'll see an "Attachments and other settings" link that will allow you to make the attachment.

If you like, I'm happy to provide detailed instructions for how to run Arduino IDE 2.x from the command line, but I'd first need to know which operating system you're using.

Im using win10

OK, here are the instructions for running Arduino IDE 2.x from the command line on Windows and getting the output:

• Start File Explorer (AKA Windows Explorer).
• Open the Arduino IDE's installation folder (usually C:\Program Files\Arduino IDE or C:\Users\<user name>\AppData\Local\Programs\Arduino IDE)
• In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
• Click “Open PowerShell window here” (or “Open command window here” if using Windows 7). PowerShell (or cmd if using Windows 7) will now open with the current directory set to the Arduino IDE installation folder.
• Type & ".\Arduino IDE" (or if using cmd, type "Arduino IDE").
• Press Enter. Debug output should now be printed to the PowerShell window as the Arduino IDE starts (or fails to start).
• Wait for the Arduino IDE to finish starting, or failing to start.
• Switch back to the PowerShell window if the Arduino IDE window took the focus.
• Right click on the title bar of the PowerShell window.
• Click Edit > Select All. This will select all the text in the PowerShell window.
• Press Ctrl + c. This will copy the contents of the PowerShell window to the clipboard.
• In this Arduino forum thread, click on the reply field.
• Click the </> button on the forum toolbar. This will add the forum's code tags markup to your reply, making it easier for us to read.
• Press Ctrl + V. This will paste the output between the code tags.
• Move the cursor outside of the code tags before you add any additional text to your reply.
• Click the "Post" button.

Hopefully that will give us some information we can use to help you with the problem.

Please let me know if anything is unclear.
