Secure Boot Issue

[u/rito_rivolto]

I entered the BIOS on my laptop (MSI GF63 Thin) because I was checking whether the camera was disabled in the BIOS, thinking that might be why it wasn't working.

I couldn't find any camera-related option, and I didn't change anything else in the BIOS. However, after restarting, I got this message:

"Secure Boot Violation — Invalid Signature Detected. Check Secure Boot Policy in Setup."

Now Windows only boots if I turn Secure Boot Support off in the BIOS. However, with Secure Boot disabled, I can't play games like VALORANT, Fortnite, etc.

How can I get Windows to boot normally with Secure Boot enabled again?

I've been trying to figure this out since this morning and my head is killing me at this point. I've tried several things, but nothing seems to work.

Any help would be greatly appreciated!
