Error when importing flask_socket-io : AttributeError: module 'collections' has no attribute 'MutableMapping'

With a python file that is just:

from flask_socketio import SocketIO

I get the error:

I saw in other threads that collections.MutableMapping has changed to collections.abc.MutableMapping in python >=3.1. I have tried the following solutions to no avail:

1. Upgrade dependent packages:

pip install --upgrade pip
pip install --upgrade wheel
pip install --upgrade setuptools
pip install --upgrade requests

2. Reinstall flask-socketio

pip install flask-socketio

I tried to reinstall the eventlet dependency with upgrade:

pip install --upgrade eventlet
Requirement already satisfied: eventlet in c:\...\python\python310\lib\site-packages (0.33.3)
Requirement already satisfied: greenlet>=0.3 in c:\...\python\python310\lib\site-packages (from eventlet) (2.0.2)
Requirement already satisfied: dnspython>=1.15.0 in c:\...\python\python310\lib\site-packages (from eventlet) (1.16.0)
Requirement already satisfied: six>=1.10.0 in c:\...\python\python310\lib\site-packages (from eventlet) (1.16.0)

None of these options work. How should I fix this error?
