This seems to be a duplicate of Issue40494. It has already been fixed in Python 3.10, and in Python 3.9.2 (which isn't out yet). You can see the what's new for it here https://docs.python.org/3/whatsnew/3.9.html#notable-changes-in-python-3-9-2.

The expected release date for Python 3.9.2 is Monday, 2021-02-15 according to PEP 596 https://www.python.org/dev/peps/pep-0596/.

For now, I guess you'll have to use the old typing.Callable, then update it in newer versions of Python.

I'm assuming you are currently using python 3.9.0/3.9.1, which has this bug. I'm unable to reproduce it on Python 3.10.
