Another streamlit 1.5 won't run at all

Using Streamlit
1

I’ven been working on a streamlit app for a while. Works fine. Updated to 1.5 today (accidentally, actually), and streamlit would not start:

Windows, conda env. python 3.9.

python -m streamlit.cli run c:\Data\Projects\App-WOS_US_Forecast\forecast_ui.py

rollback to 1.4 allows it to run again.
