Google Vision's Python Client Quickstart throws TypeError: bases must be types

I am trying to run the quickstart from Google's Vision python library locally. However, when I run python3 quickstart.py I get the following error:

Traceback (most recent call last):

TypeError: bases must be types

What I know is:

I am not sure at what point in this stack trace that the error is occurring, or how to fix it.

According to @DazWilkin's comment, downgrade the protobuf package as follows.

pip uninstall protobuf
pip install protobuf==3.20.1

It worked just fine for me. tensorflow and protobuf versions were incompatible in my case.
