I recently added a Music section in Plex, Started adding my music and i got to G and added Genesis and it stopped scanning new albums / media. I have tried to delete Music from the library by clicking … Delete i check the box and click delete but the library is still there and so is all the album icons, tracks, info etc. It will not Go. Iv tried removing the folder and adding an empty folder again no luck Icons, tracks are still there. I added a New library and called it Music - MP3 i pointed it at an empty folder NOTHING in it tried to delete and Again the same thing it does not get deleted. SO i have now put the files back in the original Music folder and they all play ok i Removed the Genesis folder Optimised Plex, Scanned Files, Cleared Bundles and Emptied the trash yet its still there.
This is the response i got for the person who created the docker,
Just a guess but maybe the scraper is having a problem with some character in your file or folder name.
i have done a fair bit of python coding in the past and python 2 is a ■■■■■ for encode/decode (defaults to ascii) looking at the traceback i would def say you have a dodgy character in the filename/foldername/metadata for one or more of your audio files, tricky part is finding out which one(s) 
tbh plex should be written to cope with this scenario, so strictly speaking this is a plex bug.
So can someone at Plex please explain whats going on and how to resolve this issue
TIA
