1 year ago Without any relevant code or more information it's near impossible to debug this. Also, I do have a feeling this is more something in your project than it is something in Xamarin.Forms.
Try running your app through TestFlight or build it with the Release configuration and see if you can uncover something like that. I you haven't so already, it might help to use some service like App Center Crashes and see if that gives you a lead on where it crashes. Additionally you might be able to check the device logs. Good luck!

The app was rejected by Apple review team with:
"DESCRIPTION OF PROBLEM The app review process rejected the OkMap Mobile app because it crashes on startup. This is the received message:
"We were unable to review your app as it crashed on launch. We have attached detailed crash logs to help troubleshoot this issue.
Review device details:
In my tests, the app works fine both in debug and on the following physical devices: iPhone X - iOS 16.5.1 iPhone SE - iOS 16.6 iPad Air - iOS 12.5.6
I've symbolized the crash report that Apple was sent me (see ### Crash log). I need some information to understand the crash log.
Steps to Reproduce
Launch the app and verify if the app crashes.
Expected Behavior
The app should not crash.
