Apple TV 4K. Not playing personal music library

Today when we turned on our Apple TV 4K (2nd gen) our playlists when selected would not play. I restarted the device x2 and reset my router. All other apps are working but while I am able to navigate the library I have no music will play even if I choose a single song. Further we have three of these devices and the same issue presents itself. I have checked my MAC, iPhone, and iPad and all are playing fine. So to me it seems localized to the Apple TV device.

Is this a know bug, and is there a fix? I have a neurodiverse adult in my home and music is his life and the lack of it (Their playlists have to play on the TV) is causing significant stress.

I look forward to this communities support to find a quick resolution.

If it is because of obsolescence then fine, I just need to know.

Thanks.
