I'm seeing a similar issue on a laptop which was working fine until I reinstalled Ubuntu Jammy with ZFS (with full-disk encryption enabled). Sometimes it freezes for several seconds, but sometimes I wait hours and it never recovers.
I don't think this is a gnome-shell issue, but I'm unsure how to go about troubleshooting it.
