I discovered recently that one way to make the Wayland login options vanish is to have any bug in the mutter eglnative backend that triggers an assertion. gnome-shell doesn't treat this as fatal, but it does remove Wayland options from the list of login sessions in that case.

So this assertion from your log might be relevant:

loka 08 10:50:57 username-System-Product-Name gnome-shell[2848]: setup_framebuffers: assertion 'width > 0' failed

Or it might be one of the other gnome-shell assertions in your log.
