I'm really struggling with an issue in Visual Studio Code where it just won't recognize the Python virtual environment I'm working with. It continuously refreshes without locating the venv, which also means the language server (Pylance) isn't functioning. The entire Python setup seems broken because it just keeps loading, even in projects without a virtual environment.
Whenever I open VS Code, I notice a command prompt window that flashes, staying on screen only for a second or two before everything freezes up.
I've tried a bunch of solutions already, including deleting and reinstalling Python extensions, upgrading and downgrading Python versions, switching the Python locator in settings, clearing workspace cache, and reinstalling everything multiple times. But nothing seems to stick— the problem comes back soon after. I'm hesitant to hardcode the venv paths since I manage several projects simultaneously. Any advice on where the issue might be?

I faced something similar when I had multiple installation paths for Python in Windows Environmental Variables. You need to have both the Python folder and the Scripts folder in your PATH, but only point to one installation. Make sure your paths are set correctly; if they’re not, that can definitely cause issues.
It sounds like there could be a corruption or a conflict with your Python extension. A clean reinstall of VS Code might help—make sure to delete the config folders in the AppData. Also, check if you have multiple Python installations because those can really mess things up. That command prompt flashing hints that something is crashing when it tries to detect the environments.
That flashing command window is a big clue! It usually means something's running in the background and failing. Try checking the VS Code output panel: go to View > Output and select "Python" or "Pylance" in the dropdown. You might find an error message that explains what's going wrong. Also, ensure your PATH environment variable isn't pointing to multiple Python installs—run `where python` in the command line and see what shows up.
