Hi @un_francais. Thanks for giving the Arduino IDE 2.0.0 release candidate a try, and for your report.

Please tell me which operating system you are using. That will allow me to provide you with the correct instructions for the next step in troubleshooting the problem you are experiencing.

It's Windows 10 Professionnel 21H2

OK, great. 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\<user name>\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".
    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 the Arduino IDE starts (or fails to start).
  7. Wait for the Arduino IDE to finish starting, or failing to start.
  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.

I fail at the point 5.

So i uninstall Arduino 1.8.19 and Arduino IDE 2.0.0-rc8 and also i delected all arduino in C:/ and AppdData.

After reinstallation, i have that in my bordel selector :

I think there was a conflict with the old files of the old version with the new

The installation took about 45 minutes;

thank you for your time, I'll let you close the topic unless you have other questions for me?

Do you still want the file ?

If you have the name of a file you wish to observe, I can give it to you I did not clean my trash.

Unfortunately I could not give you an answer before Monday.

(have a good weekend)

The reason for this is the Arduino IDE must download some data from the Internet before it can populate these. Arduino IDE 1.x was designed so that you had to wait for the downloads to finish before you could even start using the Library Manager and Boards Manager dialogs, but Arduino IDE 2.x does not, which can be quite confusing at times. There is actually work in progress now to communicate to the user that the downloads are in progress:

(it is being done as part of a fix for separate bug)

Wow! That is unexpected. Do you have a really old computer or something?

I guess you could have used that time to learn how to use PowerShell instead.

But anyway the important thing is that the IDE is working now. Great job on finding a solution to the problem!

Thanks for the offer. I don't want to put you to any further inconvenience. My primary goal was to help you to fix the problem and you have already accomplished that.

I can guess that the problem you experienced was either this:

Or this:
