Simply going to Settings -> Music causes the Settings app to freeze.
Also, I can no longer sync music from my Mac to my iPhone - it never shows the "Sync" button.
And, if that's not ugly enough all by itself - none of the music that's already loaded on my phone responds to the Play button within Music.
Using iOS 17.0 beta 7 (21A5319a)
Myself and others are experiencing issues with the music app, music settings, and TV app on iPhone. All of them freeze up.
The workaround I found on Reddit is, add a second language in the settings app, then delete that language. For some reason that fixes the freezing and should allow you to sync content too. I found if I reboot the phone I have to do that trick again.
