Players attempting to start Modern Warfare 4 on Steam report persistent BIOS and TPM (Trusted Platform Module) errors despite updating firmware and enabling required security features like Secure Boot. These errors prevent game launch, affecting access for some users. The issue appears widespread enough to warrant community attention and may require developer fixes or detailed troubleshooting. Players encountering these problems should watch official channels and forums for updates to avoid extended downtime.
- Errors persist even after BIOS updates and TPM activation.
- Secure Boot enabled but game still prompts for BIOS updates.
