A Call of Duty player using an ASUS Prime B760M-A AX D4 motherboard with BIOS 1836 and an i5-14400F CPU reports repeated failures in the game's attestation check. Despite meeting all secure boot and TPM 2.0 requirements and keeping BIOS updated, the player’s system is flagged, restricting matchmaking options. Multiple contacts with Activision support have yet to resolve the issue. This case underscores ongoing compatibility challenges with Call of Duty’s anti-cheat and system verification processes, which can hinder player access and disrupt gameplay experience.
