Apple Music app stuck on Apple TV 4K

I have the Apple TV for over 3 years.

Apple music worked perfectly until now.

A few days ago I tried to play music.

The music app opened but shows only the top menu, and the rest of the screen is empty.

The app is completely frozen and not responding to the remote control.

I read all previous post about similar issues so I tried:

• Kill the app
• Turn-off and on the apple TV
• Restart Apple TV
• Plug out and in of the electric socket
• Restart the Internet switch and router
• I verified all other apps on the apple TV (Like appleTV+, Netflix, etc.) are working properly.

I'm afraid the app is corrupted but there is no way to reinstall it since it is a build-in app, hence can't be uninstalled.

The only option left, which I don't want to do, is reset the AppleTV to factory defaults.

Any other advice?

Thanks!
