Windows 10: PC won’t stop crashing as soon as I start it

Hi!So I was using my PC as normal and it suddenly crashed, I restarted it but now anytime I turn it on the blue screen with error code 0xc000021a pops up right away.I tried multiple times to repair it by using command prompt as it wont let me restart the pc or go into safe mode. I also tried restoring the system but it won’t work. I didn’t download any updates recently, my friend suggested I try to update my windows 10 to 11 but I’m not sure how to do that since it goes right to windows repair system. And then crashes again when I make it go back to windows.My last option is to install windows

Suggest any methods to stop Firefox from crashing. It crashes right after starting, no more than a second or 3..

Any cache, plugins, antivirus things that might cause it? It is very, very annoying...
