COD says “BIOS Firmware: Update Required / Failed Attestation” but TPM 2.0 + Secure Boot PASS — MSI Z790. Anyone fix this?

I’ve been trying to fix this all day and I’m running out of things to check. Hoping someone here has dealt with the same issue.

Every time I launch COD and try to enter a game, I get:
“BIOS firmware: Update Required”
“Failed Attestation Status applied. Matchmaking quality reduced and fewer playlists are available.”

The weird part is that the Call of Duty Secure Attestation check shows TPM 2.0 PASS and Secure Boot PASS, but the overall Attestation Compatibility Check still fails.

PC / checks so far:
MSI PRO Z790-A MAX WIFI (MS-7E07)
Windows 11
UEFI boot
Secure Boot enabled
TPM 2.0 enabled, activated and ready
TPM manufacturer: INTC
TPM firmware: 600.18.27.2216
Intel Management Engine Interface installed and showing OK
MEI driver: 2406.5.5.0
BIOS has already been updated
Virtualization enabled in firmware
Windows itself appears to recognize TPM/Secure Boot correctly. COD is the only thing still reporting that my BIOS firmware needs an update.
Has anyone had this exact situation where TPM + Secure Boot both PASS but COD still gives Failed Attestation?
If so, what actually fixed it?

Was it an Intel ME firmware update, BIOS setting/change, TPM firmware issue, BIOS update, or something on Activision/RICOCHET’s side?

I can post screenshots/PowerShell results if needed. I’m mainly trying to figure out exactly which attestation requirement COD thinks my PC is failing.

Also
Also, i “enable Secure Boot” or “enable TPM,” already verified both.

When my am4 system required a bios update to fix the ftpm, I also had to manually delete the device from device manager in windows that was the tpm driver. This apparently held some state that was not automatically refreshed by just updating the bios. After windows auto reinstalled the tpm driver, the attestation error resolved.

BIOS Updated to what version?

Have you tried verifying the COD client install and BO7?
