boost_python3 problem

[MianDoesCoding]

MacOSX catalina 10.15.4, last xcode, last python from python.org and so on.
Except for bought soft (office, photoshop, ..) , I keep always all my soft up do date with the last release as far as I can.

Hmm, Seems tricky. I'm not sure what the problem is if everything is up to date. If you want, i could post in a bit and put a link to this post to see if anyone could help :) good luck!
