Hi all 
It looks like a breaking change in one of Streamlit library’s dependencies (protobuf) is the cause of this issue. I’ve notified the team who are working on a fix. A patch to fix this issue will be included in our release next week.
Until then, a temporary solution (thanks @whitphx!) is to include the following in your requirements.txt:
protobuf~=3.19.0
Best, 
Snehan
