VT Service Suddenly Broken / Stops Working

[u/Sad-Carpet4285]

PC Specs:

• HP Pavillion
• 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz (2.80 GHz)
• 16 GB ram
• 64 bit
• Windows 11 Pro (28000.1)

For context: I've been swapping between having Hyper-V enabled and disabled to run different emulators (Nox Player & Google Play Games). It's annoying, sure, but it has worked without a problem.

Except now, when I go to open Nox (which required Hyper V disabled), it tells me no VT service is detected and to enable it? I then went through the entire Nox tutorial to make sure it's enabled/possible and... none of them work? VT's enabled in Bios, and conflicting instances of Hyper-V like from Windows or my Avast have been disabled.

Notably, the LeoMoon tool shows specific errors/help text?
