Something wrong happen when I execute the command "streamlit run my_script.py"

When I execute the command “streamlit run my_script.py”,a fatal error in launcher happen.I have no idea what makes this error happen

Have you checked the obvious things like python version, streamlit version, and both are 64-bit. Does streamlit hello work?

If you are able, please post a minimal sample app to reproduce this error?

Thanks,
Arvindra
