I've tried to restart the kernel using the "Restart Kernel"-Function

I'm using Debian 11 on a raspberry 4 and spyder 4.2.1

Hey @PythonUser112, thanks for reporting. Please remove this directory and try again:

/home/buddha/.local/lib/python3.9

It seems the Python packages installed there conflict with the ones from your Python distribution.

Let us know if that works for you.

Closing due to lack of response.
