Hey there, thanks for reaching out and welcome to the Streamlit community! 
This “Spinning up manager process…” issue is a common hiccup on Streamlit Community Cloud. The first thing to try is rebooting your app from your workspace or the app’s Cloud logs—this often resolves temporary deployment glitches. If that doesn’t work, deleting and redeploying the app is the next recommended step, as confirmed by multiple community threads and official docs. No need to worry—this usually doesn’t affect your code or analytics, but always keep a backup just in case.
If the problem persists after rebooting and redeploying, it could be due to a temporary infrastructure issue on Streamlit’s side, or your app may be hitting resource limits. You can check the app logs for more details and monitor the Streamlit forums for outage reports. For more info and step-by-step instructions, see the official guidance on rebooting your app and related community discussions. Community members, feel free to jump in with your experiences or tips!
