LottieXamarin on Xamarin Forms, my Lottie animation crashes on iOS

🐛 Bug Report

on XamarinForms / iOS, I get an exception when using a Lottie animation; I paste the complete call stack here below. On Android, everything works fine; I have no idea, if the iOS version just can't find the resource or what's happening. If I try to reference a non-existing file, iOS keeps crashing, while Android just does not show anything. What can I do?

[0:] An error occurred: 'Could not create an native instance of the type 'Airbnb.Lottie.LOTAnimationView': the native class hasn't been loaded.
It is possible to ignore this condition by setting ObjCRuntime.Class.ThrowOnInitFailure to false.'. Callstack: '  at Foundation.NSObject.InitializeObject (System.Boolean alloced) [0x0002e] in /Users/builder/azdo/_work/1/s/xamarin-macios/src/Foundation/NSObject2.cs:247
