Public bug reported:

Recently i updated muttter-common(42.9-0ubuntu7) and
libmutter(42.9-0ubuntu7), gir1.2-mutter(42.9-0ubuntu7) on Ubuntu 22.04
LTS after which when I try to login the following issue happens but only
when I use the nvidia driver and X11 this does not happen when using
Wayland or Nouveau driver.

The problem is when I try to log in, tested on nvidia drivers 535 and 545.
in most cases: Desktop freezes for ~15s, then ~4s black screen, then ~20s grey 
screen, then works as expected.
In some cases: Gnome locks up and needs a hard reset (mouse cursor does not 
freeze)
In rare cases: Works as expected, except high CPU usage

There are new error messages in the syslog file that weren't there before:
gnome-shell[...]: Window manager warning: MetaSyncRing: Sync object is not 
ready -- were events handled properly?
gnome-shell[...]: Window manager warning: MetaSyncRing: Too many reboots -- 
disabling
