I can't reproduce this issue, so I can't test this.

However, I am pretty sure those errors are related to updates to Pydantic. They may have been resolved by the latest release 0.103.2 according to the release notes here:
https://fastapi.tiangolo.com/release-notes/

So you may want to re-install fastapi 0.103.2.

pip install fastapi==0.103.2
