This change seems to have broken the latest version of pydash when used with typing-extensions 4.6.0. There's a bug report about this here: dgilland/pydash#197.

I did a bisect of every change between typing-extensions 4.5.0 and 4.6.0, and this was pointed out as the culprit. I've had a look at the code changes here but don't have a good enough grasp of what's going wrong that is causing this to fail.

This seems to be the relevant Pydash code that relates to the error:
https://github.com/dgilland/pydash/blob/051fe69c3e523f903a0a0ea6ca6a5c2d4b83a3e7/src/pydash/utilities.py#L577-L638
