When I press "ESC" during the question for the Python Path, I get this error:

But even if aborted, a Python venv gets used:

Running cmd: python -c "import sys; print(sys.executable)"
Successful exec
Running cmd: /home/daniel/workspace/open-needs/open-needs-ide/.venv/bin/python --version
Successful exec
Python path: /home/daniel/workspace/open-needs/open-needs-ide/.venv/bin/python
Running cmd: /home/daniel/workspace/open-needs/open-needs-ide/.venv/bin/python -c "from needls.version import __version__; print(__version__)"
Successful exec
Saved text doc of type: jsonc

But that's the wrong one. It the one from that main open-needs-ide project and not the one from our test-env project.
