Describe the problem

After using the IDE for some time, the IDE decides that even though itself identified the board/port, the board/port in question does not exist according to the uploader. In the present issue, I have used a MKR WIFI 1010 and replicated the problem with another (new) board as well. This issue has been present on multiple computers, and is usually fixed by restarting the PC.

To reproduce

1. Use the IDE 2.x for some period of time
2. Connect the MKR WIFI 1010 (without a battery)
3. Make sure that the board and port are correctly selected
4. Click on upload
5. The message Failed uploading: uploading error: exit status 1 No device found on COMXX is shown.
6. Close window and open blink sketch in IDE 1.x
7. After selecting board/port, upload again
8. You will get the same error.
   Bonus: Use another board and do steps 1-9 again

Expected behavior

The code is uploaded and the message Failed uploading: uploading error: exit status 1 No device found on COMXX is not shown in the outlet.
