I have a package using pydantic for type validation. It was working fine since March, but I got below error (see screenshot) and found that there's a new release of typing_extensions 4.6.0.
I am not sure if it is the issue of typing_extensions, but I don't get below error with version 4.5.0.
My python version is 3.10 and pydantic version is 1.10.7.

According to pydantic/pydantic#5821 (comment), it looks like this is probably a bug in pydantic rather than typing_extensions.

Very similar issue at typing_inspect: ilevkivskyi/typing_inspect#100.

Pin typing_extensions < 4.6.0
de2662e 
The latest release of typing_extensions breaks great expectations.

Great expectations is already pinned but hasn't release a new version
yet:

great-expectations/great_expectations#7974 (comment)

Pydantic and typing extensions are aware of and working on fixes as well:

python/typing_extensions#179
pydantic/pydantic#5821

Until all those pins/fixes land, let's introduce our own pins to keep
our builds passing.

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