Apparent incompatibility between python 3.11.3 & matplotlib 3.7.1

It looks like kiwisolver does have wheels for py311 on windows and we have not had many reports like this which makes me suspect that this is a local installation issue.

I would try re-installing kiwisolver.

If possible I strongly suggest using venv — Creation of virtual environments — Python 3.11.4 documentation so that if installations go sideways you can remove them and try again with minimal fallout.

If it is still not working and your workflow will support it I also strongly suggest moving to use conda or one of the other complete Python distributions.
