Install python 3.10.6. Open VS Code Insiders 1.71.0 Install Python Extension 2022.12.0

Python Extension does not recognize my python installation (both default and venvs) after having installed it with default settings and added it to PATH.

I have been consistently experiencing this problem this last ~3 weeks. Others seem to be having this same problem in this StackOverflow question

I have tried reinstalling VS code, python with different versions (3.9), as well as downgrading the VS Code Python Extension. After having downgraded VS Code Python Extension to v2021.9, I can at least run python scripts with the top right run button without it complaining that python is not installed, but Jupyter notebook is still not seeing the Python kernel.

I can run python 3.10.6 in my terminal with py or python. Even when python isn’t being detected, it seems like the environment is still “functioning”. In particular, once I’ve installed packages into the environment, even when VS Code claims the venv isn’t active, the packages are still detected by Intellisense.

Extension version: 2022.12.0 VS Code version: Code - Insiders 1.71.0-insider (8e42bda5487a953d59fab7792eedd4ca209cabba, 2022-08-16T05:18:32.502Z) OS version: Windows_NT x64 10.0.19042 Modes: Sandboxed: Yes

Looks like the problem is in get_output_via_markers.py or interpreterInfo.py?

When I try to run the failed command using any of my venv (or with my system python, tested)

in my console it seems to execute okay.

That won’t be necessary as I figured out what was going on: I unknowingly installed python 3.11 (unreleased) in my virtual environment. Afterwards I synced to git and tried to open from another machine which, of course, didn’t have a version of option that is not released yet. Your previous comments were helpful. Thank you!
