spyder: Crash when restarting kernel

Description

What steps will reproduce the problem?

When I select “restart kernel” Spyder crashes.

The crash likely relates to the fact that I cannot get the kernel to properly start in the first place always reporting this error:

“Your Python environment or installation doesn’t have the matplotlib module installed or it occurred a problem importing it. Due to that, it is not possible for Spyder to create this special console for you.”

Note that I do have matplotlib abd spyder-kernels installed in a Python venv:

% pip list | grep matplotlib matplotlib 3.5.1 matplotlib-inline 0.1.3

% pip list | grep kernels
spyder-kernels 2.3.0

I’m running on a Mac M1 in ARM64 mode.
