SIGSEGV fatal error message

[NabilG]

Form the env output, you seem to be running wayland as display server.

XDG_SESSION_TYPE=wayland

As it is discussed in other threads, either use the universal binary or change from wayland to X11.

See this thread.

Issues running Salome 9.12 on Debian 12

Hi Nabil. I took a look at the thread you referenced. Indeed, if I switch to a x11 session Salome runs fine and all the GUI buttons appear to be working. So, the problem is apparently wayland. I am quite surprised to be the only one having this problem, as wayland is now the standard with debian 12. However, thank you very much for the suggestions, you helped me a lot. Andrea P.S.: for reference, here it is explained how to switch to x11 from wayland in a reversible way.
