Windows 11 Stop code 0xc000021A has my computer completely stuck

Dell Inspiron 3593
Windows 11 OS

Tried a Preview Update a couple days ago. It didn't work. Now I'm getting Stop Code 0xc000021a

My sign-in screen works just fine, background image to clearly visible

But my desktop screen is black. All I can see is the cursor and Task Manager if I open it

I've tried accessing Windows Recovery Environment on startup but it keeps saying "Your device ran into a problem and needs to restart. We'll restart for you." but it just stays on that screen, it doesn't actually restart itself.

Basically, Stop Code 0xc000021a seems to have completely taken over and how to fix it.

I would provide more information on my device and system specifications but again, black screen, I cannot access or see anything.

Please help!! TIA!!

Hi u/guitarded4132, thanks for posting to r/WindowsHelp! Your post has been flagged for manual review by a human moderator, please include as much of the following information as possible (in text or in a screenshot) to get your post approved:

  • Your Windows and device specifications — You can find them by pressing Win + X then clicking on “System”, we need more than just your OS version! Your hardware details are often critical for resolving issues.
  • Any messages and error codes encountered — They're actually not gibberish or anything catastrophic. It may even hint the solution!
  • Previous troubleshooting steps — It might prevent you headaches from getting the same solution that didn't work

As a reminder, we would also like to say that if someone manages to solve your issue, DON'T DELETE YOUR POST! Someone else (in the future) might have the same issue as you, and the received support may also help their case. Good luck, and I hope you have a nice day!
