Update 2023-03-04: A new version of the 5.19 kernel, 5.19.0-35-generic, will now boot into a GUI desktop instead of leaving me with a completely unusable system, BUT, there is no working Vulkan implementation, as if the amdgpu driver still failed to load so the new kernel did a fallback to the radeon driver, I would guess.
Partial output from vulkaninfo with 5.19 kernel:

------------
I recently installed apt upgrades, and among the upgrades, was the 5.19.0-32-generic kernel. I also still have installed the 5.15.0-58-generic kernel.
Every time I try to boot with the 5.19 kernel, my AMD Radeon R9 280 GPU fails to init. This results in the computer effectively getting 'hung' part way through the kernel boot as X or Wayland, whatever should start up, doesn't. The kernel keeps running (I can see the hard drive light occasionally flash on my case, and the kernel logs continue after the point of the apparent hang - although kernel messages stop getting output to the console - to see the messages, I have to reboot with 5.15 then use journalctl to review the previous boot messages).
It inits fine with the older kernel. Not sure what the root cause of the failure is. Found this in kernel boot logs (via "journalctl -b -1" to get the logs for the previous boot, that failed), which I think is indicative of the problem:
