@queengab i got him back with this ( screwed up mine again to see how i could get it back )… :
You will need to update the ytdl-core to the latest.
cd /data/plugins/music_service/youtube
and modify in package.json under ytdl-core from whatever number is there to 3.2.0. Save it and then run in the same folder from the command line: npm --depth 9999 update. Reboot This seems to work for me.
