GarageBand. And no I haven’t tried completely restoring the phone from a back up. Everything but GarageBand functions fine. They updated the app and now it doesn’t work on older models of phones. Also IOS 11 slowed down older models and put in a large amount of glitches.
Okay, so it seems that you need to address a problem with GarageBand. At least you are finally identifying the problem. The troubleshooting steps that I provided are what you need to try to address the problem, or you can follow the steps here, If an app you installed unexpectedly quits, stops responding, or won’t open - Apple Support
I have an iPhone 7 and was able to open GarageBand. Have you tried deleting the app from the Phone and then adding it back again? You are going to need to also check in the App Store to see if you have the latest version. Seems to be something with your device you need to troubleshoot.
