Blade 15 (RZ09-0485X) persisting issues with TPM 2.0 attestation

Hello,

 

I’m having issues with TPM 2.0 attestation error messages when attempting to play Call of Duty Warzone and ranked play since Friday. Last successfully played on Thursday. I can’t see what  could have changed, unless there is a stricter version of TPM implemented in the game. I have been unsuccessful with all my attempts:

-Update customer firmware and installed latest bios: https://mysupport.razer.com/app/answers/detail/a_id/14657

-Windows up to date

-Reset TPM activation keys with tpm.msc command (had to re log/setup all my MS services again)

-Reinstalled the game

 

Still the TPM error message issue persists. TPM 2.0 is active. Is there a new BIOS update required here, or  TPM specific update? I see TPM updates for other models, but nothing for the Blade 15” 2023 model listed in the title.

Thanks

From their TPM guide, it seems like a BIOS update is required, but I’m on the latest available BIOS update version according to the latest customer firmware updater
