Windows 10: PC turns off after entering windows pin and now won’t turn on

Just updated to windows 11 and My PC turned itself off after entering my windows pin. Originally I thought maybe the surge protected it was plugged into went bad and changed the outlet it was plugged into and it seem to be fine. But then I moved my PC to the room I normally keep it in. I plugged it in and turned it on, as soon as I entered my pin, again it shut down and now I can’t turn it back on. I’ve tried multiple outlets and they all work but my computer still won’t turn on. Why is it shutting down as soon as I enter my pin and why can’t I turn it on now??

Windows defender is turned off and won`t turn back on

Windows defender on windows 10 enterprise won`t turn on. This happened shortly after i updated it; when I try to turn it on it says:

This app has been turned off and it isn't monitoring your computer.

And right underneath it, it says:

If you are using another app for malicious and unwanted software use Security and Maintenance to check that app`s status.

Need for a response ASAP, thanks
