Uninstall unifi controller

Ive install unifi and have now stopped the controller from running and stopped it from running on boot, restated hassio but can not uninstall unifi, the UI seems to hang requiring a refresh to get it back. Any ideas please how I can delete or force a delete, Im using a raspberry pi 3 B+.

I am having the same problem. Did you find a solution?

Yes I did, I bought a NUC not had a single issue with UniFi since. Rock solid.
