I tried the Device Guard suggestion and it didn't work. I do appreciate the suggestion.

So you added all those registry entries in the script? Glad it was useful in some way, even if it had little impact. I use that script on my computer given the game requires HVCI / Memory Integrity, DMA Protection, and VBS to be enabled in the operating system itself, not just the firmware / UEFI. Not all motherboards support HVCI / Memory Integrity. Sometimes it's not enabled by default when you install Windows 10 /11. It is a generic error, so as a process of elimination it has to be something else, given it's tied to the anti-cheat software.

You could enable that in the registry, but it might not do anything, if it's disabled in UEFI, or your motherboard doesn't support it:

"If you select Secure Boot with DMA, memory integrity and the other VBS features will only be turned on for computers that support DMA. That is, for computers with IOMMUs only. Any computer without IOMMUs will not have VBS or memory integrity protection." -> https://learn.microsoft.com/en-us/windows/security/hardware-security/enable-virtualization-based-protection-of-code-integrity?tabs=reg
