Getting TPM Error from Windows 10 KVM

[guff666]

I have a Windows 10 KVM installed on PVE 7.1-10. It's running fine, but I've just noticed an error in the System log:

The device driver for the Trusted Platform Module (TPM) encountered a non-recoverable error in the TPM hardware, which prevents TPM services (such as data encryption) from being used. For further help, please contact the computer manufacturer.

It's recorded as TPM Event ID 15

Any idea on solutions? Delete and recreate the TPM? The config is:
