I resolved this by doing:

pip uninstall grpcio conda install grpcio conda install grpcio-tools

This correctly installed the M1 versions. For info, see: https://stackoverflow.com/questions/72620996/apple-m1-symbol-not-found-cfrelease-while-running-python-app

I was using Python 3.9.12 on a Mac Studio running macOS v12.5.1

@bmwilly I found that this error only happened in miniforge3. To work around this error, you could use Anaconda.
