Well, that sounds far worse than what happened to me.
After update on 11th, (12th for me), black screen with a little white dialogue box in upper left part of screen saying Internet Explorer wasn't responding.
Nothing was working, except for some reason, I was able to CTRL/ALT/DELETE and pull up Task Manager, (weird).
I kept rebooting to log in screen and logging in, but only got the "BLACK SCREEN AND ERROR MESSAGE TOP LEFT".
So I was getting upset that the dreaded update scenario had finally befallen me. Then I remembered to power cycle 3 times to get to the recovery screen.
Didn't work at first, had to do at least 3 full power cycles of 3 cycles before that pretty blue recovery screen with options under advanced came up!.
So I quickly did a restore point back to the 7th. Worked like a charm, got to desktop and everything was awesome, so I paused updates till I could figure out
what was going on. 3 Hours later I tried same updates and had no problem, (weird?).
Now another issue has arisen, chiefly Microsoft Edge. I download it, save it, then open it up, .....nothing!. Did this like 3 full times before it would even begin
to install. OK, got it installed right?, ... Nothing when I open it, just nothing, lol.
Don't understand why Edge isn't Compatible with this 1809 Enterprise LTSC\ 2019 Server\ Windows 10 RS5,....LOL.
Update; 10-15-22,
Got Edge working fine, a command line tutorial fix worked for me, ...everything is just zipping along fine now.
