Hi,

I have same issue here.

I think issue that version in matplotlib/_version.py is set to 0.0:

❯ cat /usr/lib/python3.10/site-packages/matplotlib/_version.py
# coding: utf-8
# file generated by setuptools_scm
# don't change, don't track in version control
__version__ = version = '0.0'
__version_tuple__ = version_tuple = (0, 0)
