IDE hangs on startup

Issue, Arduino 2.3.4 not opening up

Using Win 10 pro

Last working version was 2.3.2 , I kept ignoring the upgrade to 2.3.4, after about a month, i must of hit skip upgrade, never worked from there.

So I gave in after trying a few youtube videos to fix it and nothing worked.

I uninstalled 2.3.2 thinking, okay, guess i will download 2.3.4 and upload the program to the new version and that would fix it....same issue:

Once i open the file, the logo just go in and out, not frozen, but just refuse to open.

I reviewed :

https://support.arduino.cc/hc/en-us/articles/4410177782418-If-the-Arduino-IDE-freezes-or-is-unresponsive.

and a few videos that just not making it clear what specifically needs to be done to fix or correct the problem.

Any suggestion or fix would be appreciated.

*********I am not a tech or Arduino kit builder, electronic buff, etc, just an end user that use the product to run a program and trying to avoid all the drama.

Thanks in advance.

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

Please do this:

1. Close all Arduino IDE windows if the IDE is already running.
2. Start Windows "File Explorer".
3. 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".
4. In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
   A context menu will open
5. Select "Open PowerShell window here" from the menu.
   Windows PowerShell will now open with the current directory set to the Arduino IDE installation folder.
6. Type the following command:

   & ".\Arduino IDE"
   

7. Press the Enter key.
   Debug output should now be printed to the PowerShell window as Arduino IDE starts.
8. 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).
9. Switch back to the PowerShell window if the Arduino IDE window took the focus.
10. Press the Ctrl+Shift+A keyboard shortcut.
    This will select all the text in the PowerShell window.
11. Press the Ctrl+C keyboard shortcut.
    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 <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.
    
    
14. Press the Ctrl+V keyboard shortcut.
    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.
