Hello, thank you for submitting this issue. This surely looks like an odd edge case. Just to confirm, does the same issue occur with the python environments extension deactivated?

[merll002]

The issue can't occur without it because the python environments extension provides the virtual environment, without it all works fine.

I am guessing this might be related to microsoft/debugpy#1980, microsoft/vscode-python-debugger#820

Can you confirm what version of the debugger (ms-python.debugpy) you're using?
