In the second screenshot, it looks Streamlit is running correctly (if you copy and paste “http://localhost:8501” into a browser, you should see the Streamlit demo app). If you want to then run your own Streamlit app (it looks like that’s what you’re trying to do when you enter streamlit run streamlit_app.py), you’ll need to first do control+C to escape the Streamlit CLI that you started when you entered streamlit hello.
