Raspberry pi Bookworm, latest upgrade and update. I upgraded to Python 3.13.7 from 3.11, and had to do this in virtual environments since the normal upgrade hasn't gotten that far yet.
In the process, Thonny is broken. The "Programming" menu selection does nothing, and if I run it from the terminal I getAny clue as to what happened?> Thonny

During handling of the above exception, another exception occurred:

Any clue as to what happened?
No.
But I can suggest that since the Thonny IDE is a third-party application not directly developed or supported by Raspberry Pi you might get an informed response by raising an Issue with its developer - https://github.com/thonny/thonny/issues
