Python3.10 runserver TypeError: Parameter to MergeFrom() must be instance of same class: expected google.datastore.v1.Projection got Projection.

[SQF]

I have an app on Google App Engine that uses Djangae and Django GCloud Connectors (gcloudc). After upgrading to the Python 3.10 runtime on GAE, the app works well in production, but I can't figure out how to run the local development server.
Following the documentation, I have added gcloudc.commands to the top of INSTALLED_APPS, but running ./manage.py runserver results in the following error:

A quick google search suggests installing a different version of the protobuf library. I tried versions 3.20.3, 3.20.1, 4.25.2 (newest), and even deleted the protobuf directory from sitepackages, but the error message did not change.

Here is some extra info:

Does anyone know how to fix this?
