[BUG] - streamlit crashed when running from python directly

[444B]

Describe the bug When running streamlit run main.py the files runs without issue However, when running python3 main.py it will crash and attribute it to streamlit-analytics2

To Reproduce Steps to reproduce the behavior:

1. write boilerplate streamlit file as main.py
2. install streamlit and streamlit-analytics2
3. enter python3 main.py

Expected behavior streamlit should run as expected, as seen with streamlit run main.py Confirmed that this has no correlation to the streamlit-analytics2 migration as it appears on the upstream as well

Closing this as it seems to WAI. proof: https://docs.streamlit.io/knowledge-base/using-streamlit/how-do-i-run-my-streamlit-script One should run streamlit via streamlit run xyz.py and not python3 xyz.py
