I am getting the same error on my razer blade 14 (2022), that other people have already reported for their razer blade 15 (2021).
When I boot up my Razer Blade 14 (2022) with secure boot, it gives the following message:
“Secure Boot Violation
Invalid signature detected. Check Secure Boot Policy in setup.”
Only option at the moment is to disable secure boot. Hopefully razer issues a bios update that fixes the issue with the expiration of the Windows secure boot certificates: https://support.microsoft.com/en-us/topic/windows-secure-boot-certificate-expiration-and-ca-updates-7ff40d33-95dc-4c3c-8725-a9b95457578e
@razer support: if you need any input about my device, please contact me.
