NOOOOOOOO!!!!!!’
About quarter of ten last night I was doing laundry while he was at the computer. I hear “La da di da” music and said “did your computer just restart itself?” Yes. Did you mean to have it restart? No. Next thing I know he says it is rejecting his PIN over and over. I kept my distance and encouraged him to go to bed.
He’s still asleep so I checked on it. Originally it also said to copy a six character string of numbers and letters. I did that, then I get what’s in the photo. I’ve done my old hold the button 20 seconds start several times and can’t get past this screen. I hit the windows key just for the hell of it, and nothing. We appear to be worse off than before.

That's just not knowing the correct PIN. IDK, I always use a password, but also don't use Windows 11. However, newer Windows will install updates and reboot when Microsoft feels like it - you can be in the middle of typing something and it'll just restart for updates. The fact that you had an update fail to install and it did a rollback up this thread says to me you're probably having OS corruption issues, or at least going to need some pretty technical people to fix a stuck update (maybe).
TBH the constant changes for no observable benefit and problems with updates in Windows 10 made me (at home) switch over to CENTOS7 back in 2015. Of course, this year I had to update that to Alma9 and for the first time ever, I've had Linux have random issues with updates thanks to the new dnf "fuzzy" dependencies. Flatpacks also only update (for some reason) on reboot automatically, so now even with an Enterprise focused OS I still have to do more manual things than I had to do in the old systems.
I maintain this is all because they are "fixing" things that aren't broken instead of fixing the broken things. Much of it in Windows AND Linux is "faster boots" except almost no one is doing boot timers, or booting more than once a day if things aren't otherwise broken. So if it takes 10 minutes to start in the morning - time for coffee right? If it takes an hour in the middle of the night for updates - does anyone actually care? Yet so many things get changed and weirdly broken so they can claim a 5 second boot time - I assume to compete with phones, but those don't actually shut down - they're always running so it's more comparable to waking up the monitor / screen than a boot process. And that was near instant back in 1995 IIRC so ... yea.
Windows 11 is very different from Windows XP/7 and the "good old days". I almost think someone should see (This may be enterprise only so don't quote me on it being available in the Home OS) if they can turn on the old style synchronous sequential boot process and disable all "Fast Boot". In your case I probably would actually see if they can also disable sleep and hibernate - they're already having you shut down, and otherwise you want it on anyway. So getting rid of the chances of weird stuff happening in the multiple sleep states or switching to hibernate may help also.
Also in your case - does the laptop have any biometrics you could replace the PIN with? Fingerprint reader or FaceID? Maybe buy a USB fingerprint reader? I figure swiping a finger would be "immune" to forgetting, unlike a PIN.
