For me it even deleted many of the 'pythonFiles' in the Python extension, I had to completely reinstall the extension to fix the bug. This happened to me after having multiple venvs in my project.

Env:

• Windows 10
• VS Code 1.49.0
• Extension: ms-python.python-2020.8.109390
• Shell: Windows Powershell

I can not even select my default interpreter now

Quick fix:

1. Remove extension in VSCode
2. Close all VSCode instances
3. Delete extension foldern folder in ?/.vscode/extensions called ms-python.python-{version}
4. Open VSCode again and install Python extension

In order to get this working, in Terminal -> terminal dropdown -> Select Default Shell, choose anything except Git Bash or WSL Bash.

Interestingly, the escaping in WSL bash looks better but doesn't take the /mnt/ path into account.
