My first BSOD in 20 years on Windows 11 computer

I know now what caused it.

The BFE (Base Filtering Engine) was infected with a malware. That caused my firewall to stop functioning and invited more malware into my system, and that eventually led to it.

It was kind of my fault for I was online for a few minutes without any anti-virus protection to update my drivers.

If you ever face the same problem (BFE unable to activate and kind of being grayed out), there is a freeware tool called PSTools that will reactivate it.
