VSCode doesn't Run/Debug python with pyenv's virtualenv

[AlexSkyBell]

Type: Bug

Behaviour

Expected vs. Actual

Expected: Run
Actual: Doesn't Run

Steps to reproduce:

1. install pyenv
2. install python with pyenv (I tried 3.6.15 version)
3. choose ~/.pyenv/versions/3.6.15/bin/python as interpreter
4. make a simple python script, for example:

# main.py
print('hello')

5. make launch.json with this code (actually, it's standard template):

{
    "configurations": [
        {
            "name": "Python",
            "type": "python",
            "request": "launch",
            "program": "main.py",
            "console": "integratedTerminal",
            "justMyCode": true
        }
    ]
}

6. Press F5 and make sure it does nothing

I tried last version of vscode and python extension on last Fedora 36 and last Debian 11.5.0. Also tried vscode which was downloaded from official website and snap-version. Alos tried 1.71 version of vscode and August version of python extension
P.S. If I choose standard /usr/bin/python3 then all works fine.

Oh... Python extension doesn't support debugging < 3.7? 😭
I found same bug report #19799
I try all other versions (3.7 ... 3.12) with/without pyenv - and it works fine.

Yes, sorry we gotta do a better job of highlighting it to the user: #19988. #19559 might be of interest to you.
