After not using Plex for a while I reinstall the Plex Media Server. I deleted Plex because I needed disk space. But it fails to launch.
It briefly shows in the menu bar.
Perhaps because I have been using Plex in the past? I deleted what is suggested [https://support.plex.tv/hc/en-us/articles/201941078-Uninstall-Plex-Media-Server here] under 'uninstall Plex Media Server'.
What is left to try now?
