Some Call of Duty players face a launch-blocking issue where the game demands a BIOS update even when their BIOS is already current. Attempts to enable TPM 2.0, Secure Boot, and CSM have not resolved the problem, and the codsecureattestationwizard.exe utility fails to start, preventing game access. This mirrors similar strict system checks seen in Battlefield 6 but with less flexibility. The issue suggests a bug or overly rigid system requirements, frustrating players who have fully updated their hardware settings but remain unable to play as of October 2026.
- Game demands BIOS update despite latest version installed.
- Security utilities like codsecureattestationwizard.exe fail to launch.
