Gnome freezes on login with X11 and nvidia

[David]

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

I'm sorry if I'm wrong, I've now read the problems mentioned but I'm not having any problems related to input delay, when I try to log into the session it freezes and or black screens.
