Description

Issue Type: Bug

Write some invalid python code, e.g.:


a = [1,2,3]

print(a[5])

print('done')

And launch a debugger with "pause on exceptions" set to True. As the debugger pauses and highlights the exception with a red box, attempting to edit the code while the debugger is still active very often causes the vim extension to "crash" - some things still work, but a lot of things stop working even after the debugger is stopped (for instance, it becomes impossible to delete things)

Research direction

Reproduce the issue in VS Code 1.65.2 with the Python example, pause on exceptions, and edit while the debugger is active. Trace the extension's handling of edits and debugger state, then verify that editing no longer disables commands after the debugger stops.
