- Python Environments extension version: 1.36.0
- Python extension (`ms-python.python`) version: 1.36.0
- VS Code version (Help → About): 1.1.33.0
- OS and version: Windows 11
- Python version (& distribution if applicable, e.g. Anaconda): 3.13
- Environment manager in use (`venv` / `conda` / `pyenv` / `poetry` / `pipenv` / `system` / `uv` / other): venv
- Shell (bash / zsh / fish / pwsh / cmd / other): cmd
- Remote / container scenario (none / WSL / SSH Remote / Dev Container / Codespaces): none
- Workspace type (single folder / multi-root / mono-repo): single folder
- Is this a regression? If yes, last known working extension version: unknown

## Repro Steps

Try to select a venv environment outside of the workspace folder.

## Expected behavior

The Python interpreter is selected

## Actual behavior

Error message:

```
Selected file is not a valid Python interpreter: c:\svn\modules\reporting\trunk\lrs_lra\venv\Scripts\python.exe
```

And it's falling back to the global Python installation instead.

## Logs

Tried this several time, starting 09:49 is with trace level.
