Our dependencies were updated to the new 4.6.0 automatically and it breaks Pydantic v1.9.2 with Python 3.9.16. The previous version 4.5.0 did not have this issue. The stack trace is listed below. Is this a legitimate issue on our end or a bug in the new release?

The bug is in pydantic, and a fix has already been merged for the bug: pydantic/pydantic#5826. We're just waiting for a new pydantic release that contains the fix.

pydantic v1.10.8 can now be installed from PyPI, and contains the fix.
