Windows 10: I turned off my pc mid update, now it won’t fully boot up, what do I do

My Windows 11 pc recently turned itself on a few hours after I put it to sleep, which I think was because it was updating, so I turned it off at the PowerPoint as I did not think it would be updating, but when I have tried to boot it up again more recently, it tried making changes then reverting them, then put me on the login screen, but once I logged in, it put me on a gray screen where all I could do was move my mouse, and it would occasionally flash white. I have tried turning it off then back on, but this hasn’t workedI am running on a Msi motherboard with a Nvidia 4060Ti, Ryzen 5 7600, 32

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
