I have a very similar issue (same error messages) without MobPub framework on iPhone 11 PRO (iOS 14.5) in a cordova app. I opened a stackoverflow question - maybe it helps: https://stackoverflow.com/questions/67571345/ios-iphone-11-flashing-black-and-white-while-browsler-is-constantly-reloading-r @JoeWest: could you already solve the issue?

Same problem after upgrading to iOS 17.4.1 with an iPhone 11 Pro. I am using Xcode 15.3. Before the iOS upgrade, building with Xcode 15.3 was working. Any news?
