Ubuntu 21.10 desktop, AMD Ryzen 5 3600 (3.6 GHz), 64 GB RAM
I'm having this problem both with Wayland and without.
Common to all crash situations is Firefox (default Snap install). Sometimes just Firefox will crash, but sometimes takes my entire system down with it. Sometimes I get the Firefox crash report screen, sometimes I wind up at the Ubuntu login screen, sometimes the system just freezes to the point that only a hard reset works.
I've found the "about:crashes" page in Firefox and just discovered that the last 2 weeks or so of crash reports weren't submitted, so I've now submitted all of those.
When I look at /var/log/syslog, I see far too much that I don't understand, but will happily post if someone can tell me what to look for.
Thanks in advance.
Edits below as requested. No overclocking on CPU or RAM.

BIOS
ASRock B550M Pro4
You have an older BIOS version 1.70 from 12/10/20, and there's a newer BIOS available, version 2.20 from 8/5/21, and can be downloaded here.
Note: Confirm that I have the correct web page for your model motherboard.
Note: Have good backups before updating the BIOS.
vm.swappiness
With 64G RAM, you can reduce swapping, and speed up operations, by adjusting vm.swappiness.
edit /etc/sysctl.conf
add vm.swappiness=10 (at the end of the file)
sudo sysctl -p (or reboot)
Memtest (do this after the BIOS update)
Go to https://www.memtest86.com/ and download/run their free
memtestto test your memory. Get at least one complete pass of all the 4/4 tests to confirm good memory. This may take a few hours to complete.Update #1:
