Hi,

from what you describe I had the same problem and was able to fix it. I
believe the issue is that wxpython 4.0.7.2 is outdated as the
maintainer never got a more recent version to build. However, you can
obtain version 4.1.1 for your current user via pip:

pip install --user --update wxpython

This should allow the GUI to run with no warnings or crashes.

Best,
Max
