Hello,
I have an issue with my nano 33 IOT, i can upload to the board and monitor serial when i first plug the board into my pc but after this first time i can no longer upload to the board as i get the following error:
processing.app.debug.RunnerException

The only way i am able to upload to the board again is if i restart my pc. I have tried on another pc and i dont have this issue, i am able to upload to the board as much as i like.
Any help would be appreciated!
