Importing manim kills Python extension

[jack-jjm]

Behaviour

When trying to use the Python extension with VSCodium to e.g. get function argument information about functions from the package manim, not only does this fail, but the extension seems to crash (it no longer works at all until I reload the window).

Steps to reproduce:

1. Install manim (pip install manim)
2. Import manim into a Python file (import manim)
3. Try to get argument information for any manim function, such as manim.Create

I am unfamiliar with this package and will have to investigate. To clarify, are you running a file that imports it and this is where the crash occurs?

[jack-jjm]

Yes indeed. Importing manim and then trying to get information about anything in that module seems to trigger the bug. I did a little testing but not very in depth - enough to confirm that the problem really does seem to be related to (the current version of) manim
