Hello - it seems like it freezes on Linux + Gnome if I go to the overview (with all windows visible) through the Meta / Windows key. This is with BlastFX version 2.0.2, and EndeavourOS.
and if you run it from the terminal and get it to crash, does it output any errors? I've just tried it Gnome on Fedora and it seems okay, so I'm wondering if its specific to that version of Linux...
