I already have secure boot enabled, but it still crashes
So I have TPM, IOMMU and Secure Boot enabled on my pc(I have a b450 gaming x with a ryzen 5 3600) but it still crashes and tells me that vanguard needs secure boot
Solution
Thanks man, i actually found the issue.
The problem was that It was not actually Active, so what I had to do was go in bios and change Secure boot mode from Custom to Standard, say Yes to install factory keys and say No to restart without saving(weird question tbh) and after that on System Mode it will say "User" and that is how you know it worked, you can now save an exit and it will now activate secure boot
