Private Community Cloud app stuck at “Spinning up manager process”

Hey there, thanks for sharing all those details and for your thorough troubleshooting! This “infinite loading spinner” with logs stopping at “Spinning up manager process…”—before any repository cloning or dependency installation—almost always points to a backend or orchestration issue on Streamlit Community Cloud, not a problem with your code, repo, or config. Multiple users have reported this exact symptom, and it’s often resolved only by a platform-side fix or service restart.
