VSCode cannot detect pytest unit tests, even pytest has been installed, error comes from inside .vscode-serve folder, behind company's proxy

Issue Type: Bug

Behaviour

Expected vs. Actual

Expect a list of unit tests, actually got the error message: Error discovering pytest tests (see Output > Python):

Here is the error

One strange thing I notice in the above screenshot is: it always has a “d” inside the search bar under Testing even I closed and re-open VSCode, you can see it from the screenshot above.

Here is the evidence that I have installed the pytest

Here is the error message from Output > Python:

Fix should be out in the pre-release version of the extension in a few minutes, use the following to try it out, make sure to run Python: Clear workspace interpreter setting command to clear any workspace configs, and the double-check the list to see which one we recommend:

@franva Thanks for the info, I have ensured interpreters with issues appear towards the end of the list, so they’re not autoselected. And we select the first non-conda global interpreters, if no interpreters exist in the workspace.
