Hi Giacomo, can you please provide the details of the segfault, ideally a backtrace?
We've had single mentions upstream of a segfault in libgtk-3.so in Pop!_OS 22.04 [1] with unknown solution and another one gone after reinstalling the unnamed system (there was a reference to BMLFS, but Solus is likely) [2].
