Thanks for a bug report and the backtrace. I found an upstream bug [1] about it, which leads to [2], which seems to be fixed in gtk4, but no release with that made yet.

I do not see this crash myself here for whatever reason.

I thing  I've made a small mistake. The crash happens at log out.
Comment 8 Milan Crha 2026-03-26 08:42:08 UTC 
Ah, right, it's actually what the backtrace shows, the gnome-software had been shutting down, but I did not pay much attention to it. The gtk4 change will fix it regardless whether it's on log out or log in :)
