HVCI Error when loading Valorant
So, I loaded into Valorant with zero errors, played a few games, then a few days ago I got the Secure Boot, HVCI Enabled & TPM enabled message. I managed to sort the Secure Boot & TPM Enabled errors, but the HVCI persisted. I then tried enabling Core Isolation Memory Integrity, but it wouldn't stay enabled. I then reloaded and I ended up getting a Vanguard Anti-Cheat has not been initialized with an Error Code 57 instead after updating Windows 11 to make sure I had not missed any updates, and Memory Integrity still wouldn't stay on. I then also tried reinstalling Vanguard which started even more problems...
I tried turning it on once more, and then ended up getting a Windows ACPI.SYS loop error that would not fix. I ended up re-installing Windows 11 onto my computer after attempting to debug the issue and being unsuccessful. I did not format my SSD, as it had a few files I wanted saving down (Had backed up most of the important stuff) and now have a fresh windows install with Windows.Old for my old files. The computer now runs, but I still get the HVCI error on Valorant, and cannot enable Memory Integrity without it pulling a ACPI error (Although it does boot after the crash screen. I presume its turning off memory integrity and loading).
I've tried a lot of things, and cannot get anywhere. I don't have an incompatible drivers box on the Core Isolation screen to see if there's any incompatible drivers to remove.
Any ideas?
