After upgrading from 6.10.0 to 6.11.1, VMs with OVMF TPM fail to start. Even a new VM with OVMF TPM fails with to start this same error. VMs start normally after reverting to 6.10.0.
I attached the diagnostics file generated before reverting.

Minor
That fixed it. Following that guide way back in the past will break the upgrade to 6.11.1. It is a custom script and not a problem with 6.11.1.
Here are the steps I followed to successfully upgrade to 6.11.1, for those that followed this guide to add TPM support: https://www.linkedin.com/pulse/swtpm-unraid-zoltan-repasi/
