Mickey: [WIN11] 5700x3d Security processor Attestation: Not supported?

I just recently installed the 5700x3d on my MSI B550 A Pro. I used that opportunity to upgrade to Win11 as well.
TPM is activated within bios and Windows was installed just fine. But when i now check out Device Security > Security Processor i get the message on the screenshot. I'm on the latest Bios which is about a Month old. Tried clearing the TPM 3 times already but it doesn't change anything. Does someone has a clue why i get that message?
