Describe the bug If I try to scan a folder with music outside of /storage/emulated/0/Music, in my case it's /storage/emulated/0/Audiobooks, then a message shows that it has started the scanning process (scanning 1 of 789), but then this message immediately disappears, as if the scanning process has crashed, without finishing. So the music from /storage/emulated/0/Audiobooks doesn't appear in albums, but I still can play it through folders.

Another app, that I'm using for audiobooks, has no problem with that, so I can add folders outside /storage/emulated/0/Music.

I've tried the following solutions, but it didn't help: https://github.com/RetroMusicPlayer/RetroMusicPlayer/issues/898#issuecomment-695885778 https://github.com/RetroMusicPlayer/RetroMusicPlayer/blob/master/FAQ.md#q-why-some-of-my-songs-are-not-showing-in-my-library https://github.com/RetroMusicPlayer/RetroMusicPlayer/blob/master/FAQ.md#q-why-does-my-library-shows-song-files-twice-or-no-song-at-all

Expected behavior Music in folders outside of /storage/emulated/0/Music should also be added to the library.
