Family Sharing Disaster- All wife's music gone- need help

Hey gang-

Finally got around today to enabling Family Sharing on my wife's and my iPhone. Mine an iPhone 12 Pro and hers an iPhone 13. All apps and OS up to date. Immediate disaster when I discovered that her hundreds of curated music playlists were gone from her phone- in fact her entire Music Library is empty. Her music was a combo of purchased iTunes Store songs and Apple Music downloads. I've enabled all sharing features on both our phones. We have the Apple One Premier plan for Music, apps, etc. Is there any way to restore her Music Library and Playlist to the previous state? Thanks so much!
