Details:

Matplotlib 3.5.1 is crashes at the start of its configuration with the error
in the P.S. The critical line seems to be this one: 


ImportError: cannot import name 'Mapping' from 'collections'
(/scratch/build/maneage/software/installed/lib/python3.10/collections/__init__.py)


This seems to be
<https://stackoverflow.com/questions/69381312/in-vs-code-importerror-cannot-import-name-mapping-from-collections>
a core change in Python 3.10 that is not yet supported in Matplotlib.

Strangely, the old Matplotlib 3.3.0 compiles without a problem with Python
3.10! As a result, Matplotlib will not be updated in the ongoing attempt to
update Maneage software. We'll wait until it can easily be built in Python
3.10 or someone volunteers with a patch.

P.S. full log of crash

The above exception was the direct cause of the following exception:
