After upgrade to Gnome 49.2 and login files and menus and setting not working

I would say it happens because of the removal of X11 since v49 See:

Nvidia 470xx doesn’t work with wayland, therefore it works only in Xwayland. I would guess that it is the lack of GBM support (GPU acceleration), which is a prerequisite for new GTK4 applications such as Nautilus or Gnome Settings, so a “Renderer-Collapse”.

Try to run it like this for testing purpose:

nautilus -q && GDK_RENDERER=software GSK_RENDERER=gl nautilus

In any case, it’s not a good idea to continue using Gnome with this old Nvidia GPU and the 470xx driver. Switch to XFCE, for example, which still has X11 support.
