Your message has not enough information to determine what's going on.

- How was Python installed?
- What version of macOS?
- Are you using an M1 system?
- Is the problem reproducible with a script that you can share?

I installed Python 3.8 from,  the Mac version is 11.0.1 (20B29). I have no idea before but now it doesn't work anymore. I will include the Python script here

Thanks for the update. I cannot test this myself at the moment, my laptop does not yet run Big Sur and I'm only running it in VM's on a mac mini without a webcam. 

This might be a problem with opencv, <> mentions a similar issue (with a workaround, but no clear solution)

Thank you so much for all your help. I just ran this command pip install opencv-python opencv-python-headless and it solves the problem.
