Thanks for the bug report. The most suspicious things I can see in those
logs are:

1. The amdgpu kernel driver crashed, after which gnome-shell pid 7409
wasn't heard from again:

Feb 10 19:29:14 jonathan-thompson-TR-7970X kernel: BUG: kernel NULL
pointer dereference, address: 0000000000000010

2. Some kind of internal gnome-shell/mutter bug, after which gnome-shell
pid 7569 was still running. It's hard to tell if it should have remained
functional:

Feb 10 19:33:23 jonathan-thompson-TR-7970X gnome-shell[7569]: 
meta_wayland_buffer_process_damage: assertion 'buffer->resource' failed
Feb 10 19:33:23 jonathan-thompson-TR-7970X gnome-shell[7569]: 
(../src/wayland/meta-wayland-buffer.c:710):meta_wayland_buffer_inc_use_count: 
runtime check failed: (buffer->resource)

If you can repeat the bug a couple more times then we'll have a better
idea of which to focus on.
