Error installing streamlit and when trying to run it shows pleas wait

Hi when I try to run the streamlit app on the local host it says please wait and shows an error aswell. The error is ```
Uncaught exception

TypeError: Protocols cannot be instantiated
it doesn't run the app

UPDATE: See this fix.

Hmm… I have the same issue.

I reverted back by uninstalling 1.12.0 and installing 1.11.0

$ pip uninstall streamlit
$ pip install streamlit==1.11.0
