Python debugging not working

[LordBroon]

Debugger is not starting. It is just showed and disappear immediately. No error no message. At the same run button work as expected. It worked fine last week.
I have reinstalled python extension but issues still exist.

It is similar to bug raised in: #7927

I probably have the same issue, it just randomly appeared today.
Run works, debug doesnt. Also tried reinstalling extension as well as rebooting my machine.
The issue also appears in Windows for me. In my WSL environment it still works fine.
This is my logged output:

EDIT:
Rolling back to 2021.12.1559732655
solves the issue, upgrading to 2022 brings it back

[LordBroon]

You are right - rolling back to 2021.12 solve the issue for me as well.
