Hi thanks for the reply! I guess mono got deleted somehow even though it was showing up and as updated to the latest version. The logs said mono was missing so I reinstalled it and everything works now.
I just upgraded to Libreelec 9.0 and my sonarr and radarr stopped working. I tried uninstalling the app and reinstalling but no go. SABnzbd works and I tried couchpotato and that worked but I have everything I want setup on sonarr and radarr. I would rather not have to do a fresh install of Libreelec if there's another option available.
