I'm encountering an 'Invalid signature Detected. Check secure boot policy in setup' message every time I try to boot my computer with secure boot enabled. This started after I messed with some BIOS settings and reset everything. Once I restored my BIOS settings, this error popped up, and my system boots straight into BIOS. My motherboard is a B365 HD3 Rev 1.0. I've already done a few things like resetting factory keys, changing the CMOS battery, updating the BIOS to version F5, and even jumping the BIOS pins to reset everything. I also attempted to recreate the boot path, but nothing seems to work. The computer boots up just fine with CSM and Secure Boot turned off, but I need secure boot enabled for my games. Any suggestions on what else I can try?

It sounds like you need to reinstall the secure boot keys in your BIOS. This is a key database that helps the BIOS understand which operating systems are safe for secure boot. Look for an option in the Secure Boot menu that says something like 'Install Default Keys' and give that a shot.
Just a thought, you probably don’t need Secure Boot for the games you're playing. It'd be interesting to know which games are requiring it! Sometimes, having it disabled can save a lot of hassle.
