Windows 10: 11 Update has broken my boot. Is there any way to salvage my machine?

The recent windows 11 update prevents boot, "automatic repair" pops up, no path leads to anything but "auto repair - your pc did not start correctly". I can't uninstall the update "because of pending actions". This has bricked my newish video processing workstation and ms support chat's answer was to "pay a local tech to back up my files". I don't want to lose days reinstalling software. Is there a fix for this busted update? It was cycling back to the bitlocker input screen everytime until I disabled bitlocker.

Is my graphics card broken?

UPDATE: Please see here.

I have a Sapphire HD 4830.

When I boot into XP all is initially fine and I am able to see the desktop.

However, when I click on the start bar and navigate a few steps, I receive an immediate white screen of death and a total irrecoverable lock-up.

I am confused about what this could mean and I would be grateful for any suggestions on the best course of action to test and repair the problem.

Does this sort of issue suggest that the graphics card is irretrievably broken?

 

Realtek audio broken with update, Also microsoft chat is broken

My audio is ruined with this last update, i've done every step and recommended action listed by microsoft and every suggestion on the first 20 pages of google search. Realtek is no longer showing up anywhere, like microsoft disabled it, microsoft chat is
also broken, requesting to speak with a human brings you to a couple options, all of which are broken and clicking on "chat" closes the window and nothing happens, this is absolutely disgusting, i've spent the last 4 hours trying to get my tablet, my audio,
and microsoft support to work.

Repair HyperV Machine Boot (VHDX)

Davichin
In the morning I feel my suggestions were a bit over-complicated; the easiest way should be:
- add second vhdx into the same virtual machine
- install win10 on it using ltsc iso
- add bootmenu entry for rescued system using easybcd.
Other steps are unnecessary.
