My app works find in the simulator as well.  However, both my app and the sample you sent me crash when I run it on my actual iphone.  It also crashes for apple themselves.  I submitted to the store to run it in Testflight, and they rejected it because it crashes on opening.

I am using Xamarin.Forms 5 from Visual Studio 2022 and I am targeting Android and IOS.  In summary, Android works find both on the Emulator and on an actual device and IOS works find on the simulator but crashes on my iPhone 6.  My iphone runs IOS 12.5.5 and I used the simulator 'iPhone 13 iOS 15.2'.

The sample app you sent me also crashes on my iPhone, but runs fine on the simulator.
