Hi @yumeayai. I see an error in the logs, but unfortunately they don't give me an idea of what might have caused the error. I'm going to ask you to provide the logs produced by Arduino IDE when some additional debugging output is enabled. Hopefully that will contain the vital clue that will lead us to a solution.

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

Please do this:

  1. Start Windows "File Explorer".
  2. 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)
      :exclamation: 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".
  3. 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.
  4. Select "Open PowerShell window here" from the menu.
    PowerShell will now open with the current directory set to the Arduino IDE installation folder.
  5. Type the following command:
    $Env:GRPC_VERBOSITY = "DEBUG"
  6. Press the Enter key.
  7. Type the following command in the terminal:
    $Env:GRPC_TRACE = "all"
  8. Press the Enter key.
  9. Type the following command:
    & ".\Arduino IDE"
  10. Press the Enter key.
    Debug output should now be printed to the PowerShell window as Arduino IDE starts (or fails to start).
  11. Wait for Arduino IDE to .
  12. Switch back to the PowerShell window if the Arduino IDE window took the focus.
  13. Press the Ctrl+Shift+A keyboard shortcut.
    This will select all the text in the PowerShell window.
  14. Press the Ctrl+C keyboard shortcut.
    This will copy the contents of the PowerShell window to the clipboard.
  15. Open a forum reply here by clicking the "Reply" button.
  16. 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.
    Code block icon on toolbar
    Code block icon on toolbar390×118 4.25 KB
  17. Press the Ctrl+V keyboard shortcut.
    This will paste the output into the code block.
  18. Move the cursor outside of the code block markup before you add any additional text to your reply.
  19. Click the "Reply" button to post the output.

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