Operating system: Ubuntu on GitHub Action wxPython version & source: wxPython 4.2.1 source retrieved from pypi Python version & source: Ubuntu runner, Python version 3.x which is 3.12.2

Description of the problem:

If pytest is run with a test that does import wx in GitHub actions it will crash on exit. Bisecting reveals that it only needs to include wx to make it crash. Take the import away and it works fine. Moreover, changing python to 3.11 and it will pass just fine. This is most probably related to #2479

This is demoed in repo: https://github.com/sveinse/gh-fail-wxwidgets that showcases the code and workflows that makes this fail. It sets up a very small python package that depends on wxPython and runs a very small pytest that imports wx. The master branch showcase using python 3.x which at the time is 3.12.2, while the py3.11 branch runs 3.11.8 and works fine. The repo use Actions that shows the failure and success.

Yes, this is a duplicate of #2455. It has been fixed but not in a release yet unfortunately. Paging @RobinD42 really need a release here.
