Try Python: Clear cache and reload command

[dcgudeman]

@karrtikr Do you honestly believe I haven't tried that?

[karrtikr]

Your issue is likely a dup of #22460, where specifying relative paths directly is not working: .venv/bin/python. What is the full path to your .venv/bin/python? Does each workspace have its own venv?

Try selecting absolute path explicitly using Python: Select Interpreter -> Enter interpreter path and then typing

${workspaceFolder:<workspacefoldername>}/.venv/bin/python
