Other kernel modules are probably not working either. Haven't confirmed but I wouldn't be surprised if e.g. USB didn't work either.
Going into the GRUB menu and loading the previous version (5.15.0-47-generic) works fine. I've had riffs on this issue ever since I dist-upgraded to 22.04.1 LTS. When first asking in #ubuntu in IRC I got asked to uninstall linux-generic-hwe-20.04 that was left dangling from the previous release, one thing I notice is that I don't have a corresponding 22.04 package, but since it works fine with the older kernel version I think that might not be the issue?
Also, possibly unrelated but I had a mess of nvidia drivers, installed nvidia-515 and got rid of everything else and ever since I've been having video glitches.
Here's some checks I made. I see no obvious issues, but I don't know much to be honest.

dkms status output with the non-working kernel running:
$ dkms status
nvidia/510.85.02, 5.15.0-47-generic, x86_64: installed
with the older, working kernel, it's exactly the same:
$ dkms status
nvidia/510.85.02, 5.15.0-47-generic, x86_64: installed
obviously that older kernel version on the newer kernel run looks suspect
