Segmentation fault while implementing a python program

[Carl]

I donwloaded the bin packing problem code in python (you can find the code here: https://developers.google.com/optimization/pack/bin_packing) and tried to run it. I've correctly installed ortools. However when I try to run the program, it keeps me saying "Segmentation fault: 11".

python3 bpp.py 

Segmentation fault: 11 

I tried to uninstall and reinstall the module, I also created a new virtual environment installing only ortools dependencies in it, but the problem still.

How can I solve this? Thanks

Additional information:

python3 --version 

Python 3.12.1 

pip3 show ortools

No idea.

Where does it crash ? at loading ? during the python code ?

big-sur seems to be old.
