I just managed to reproduce the crash locally. Just before the crash, the following lines are printed to stderr:

(AppImageLauncherSettings:27871): Gtk-WARNING **: 21:45:01.935: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.

Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Adwaita/16x16/status/image-missing.png: Fatal error reading PNG image file: bad parameters to zlib (gdk-pixbuf-error-quark, 0)

I think most important part here is “bad parameters to zlib”. AppImageLauncher uses its own static zlib (lib/AppImageUpdate/lib/zsync2/lib/zlib/libzsync2_libz.a) which is incompatible with public zlib (/lib/x86_64-linux-gnu/libz.so.1) that GTK was compiled against.

Recompiling AppImageLauncher with system zlib should help, but I haven’t found a way to do that. I suggest you to ask AppImageLauncher developer about that.

Attaching a stacktrace for future reference.
