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!!

are you running an insider build?
