When running the app from terminal, receive next:

$ calibre
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

So, did you try also using that?
If not, then is the app crashing also under X11 session?

Consider using the Calibre forum for Calibre issues

Or the source code repo
