Razer Blade 15 Advanced (2021) Secure Boot Violation Error

Hi Team,

 

It seems this is an issue others have run into here, but I haven’t been able to find an actual solution to this yet. When I boot up my Razer Blade 15 with secure boot, it gives the following message:

“Secure Boot Violation
Invalid signature detected. Check Secure Boot Policy in setup.”

I have turned off secure boot, which allowed me to access my computer again, but I don’t want to keep using it without secure boot. I did some digging, and it seems like this might have been triggered by Windows Security Update (KB5077181), but I’m no expert so I could be wrong. Would appreciate any help in getting this working again.

Thanks!
