Thank you for using Apple Support Communities. It seems like the Music app is not launching. One thing you can do is remove the built-in app and reinstall it. I would recommend you read this article and use it to help troubleshoot the issue.
Delete a built-in app from your device
- On your iOS device, touch and hold the app lightly until it jiggles. If the app doesn't jiggle, make sure that you're not pressing too hard.
- Tap on the app, then tap Delete.
- Press the Home button to finish.
If you have an Apple Watch, deleting an app from your iPhone also deletes that app from your Apple Watch.
Restore a built-in app that you deleted
- On your iOS device, go to the App Store.
- Search for the app. Make sure that you use the exact name of the app. Find the correct name of built-in apps.
- Tap
to restore the app.
- Wait for the app to restore, then open it from your Home screen.
If you have an Apple Watch, restoring an app to your iPhone also restores that app to your Apple Watch.
Delete built-in Apple apps on your iOS 11 device or Apple Watch
Take care.
