VS Code Insiders does not automatically detect system python interpreter on Windows 10 with WSL 2

Expected behaviour

When selecting Python Interpreter, at least 3 ought to be automatically found - Python 3.7.9 64-bit ('3.7.9: pyenv'), Python 3.9.0 64-bit ('3.9.0: pyenv') and Python 3.8.5 64-bit system version located at /usr/bin/python on WSL 2

Actual behaviour

Only the two pyenv interpreters are found, and 3.8.5 system version cannot be found. It can, however, be added manually by specifying /usr/bin/python. It also appears when running pyenv versions or python --version from bash in WSL2

Steps to reproduce:

1. Open Visual Studio Code Insiders in any directory with a python file, with no virtualenv initialised.

code-insiders .

Possibly related to Issue #15439 but I am having the opposite problem on Windows 10 with WSL 2, using visual studio code insiders.

I finally managed to set up pyenv so that pyenv shims come first in the path, and added a symlink

sudo ln -s //usr/bin/python3 //usr/bin/python

which fixed the problem of system python not appearing when running pyenv versions.

Now, however, in visual studio code insiders, the system python doesn't show up as an available interpreter (which I would imagine should be found automatically in usr/bin/python. I can add it manually though, but it doesn't persist beyond one session and still doesn't show up as an option in the drop-down.

Also just initialised a Pipfile in a repo with Pipenv, using python 3.9.0. Then deleted it, altered the Pipfile to require 3.7.7, then reinitialised it. Then, ran pipenv shell and from the virtualenv, launched code-insiders .

Code Insiders launched with 3.9.0 associated with the virtualenv... which is wrong. This didn't use to be a problem

EDIT: it just took a moment to update. Virtualenv works fine and the interpreter is correctly found. The original issue still persists, however.

@brybalicious We released a fix for the environment issue. Can you install the latest version and verify?
