All playlists deleted

@Bassem sorry that didn’t help.

  1. Have you recently moved these playlists or renamed them on your computer?
  2. Where are these playlists created (iTunes, Tidal, Beatport, etc.)?
  3. If iTunes/Music, did you copy/download the files to your iPhone or are they in iCloud?

Here’s another thread with similar issue that might be helpful.
