Hi LukeMA-127!

Do you have any operations before this issue persist?

According to your error message, the issue is related to Trusted Platform Module (TPM). You need to check if your TPM works correctly. You can try to back up your data and clear TPM. It will reset your security processor to its default settings. For more details, you can refer to:
