Run Amulet from the command line with -X faulthandler in the command and recreate the crash.
That should print out the python traceback that caused the segmentation fault.

I can also reproduce it when opening the 3D editor and provide the segmentation fault output. On my Fedora 39 Linux system it's quite random, sometimes I get it flawlessly running and sometimes it crashes. It almost seems like using the command python instead of python3.9 in the virtual environment makes it more likely to crash, which is quite absurd given they all point to the same target file. Anyway here's the output:

This is the command I run from Amulet Editor.sh - DRI_PRIME=1 __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia gamemoderun ./bin/python -X faulthandler -m amulet_map_editor
