langchain_community & langchain packages giving error: Missing 1 required keyword-only argument: 'recursive_guard'

All of sudden langchain_community & langchain packages started throwing error: TypeError: ForwardRef._evaluate() missing 1 required keyword-only argument: 'recursive_guard'

The error getting generated somewhere in pydantic

I strongly suspect it is version mismatch. So I tried upgrading packages langchain, langchain_community, pydantic, langsmith etc. But no luck.

My current installed versions shows as under:

Code:
Python 3.12.4

langchain: 0.2.3
langchain_community: 0.2.4
langsmith: 0.1.75
pydantic: 2.7.3
typing_extensions: 4.11.0

Pip check also not showing any conflict.

Here is complete trace of error. Any help would be really appreciated.
