Hi @bigbic — and welcome to the forum! 
Could you tell me your streamlit version?
streamlit --version
We’ve encountered this issue in the past, see Permission errors when running demo-self-driving and https://github.com/streamlit/streamlit/issues/301
But it should have been fixed with this PR https://github.com/streamlit/streamlit/pull/489 and released in version 0.49.0 (New Streamlit Release: 0.49.0)
