IOS no input gesture recognized

I've built a xamarin forms application. I works perfectly fine for Android.

However, when I run the application on IOS, the application launches well but I cannot enter any text in my Entries even if I tap the input field (on simulator and on my device). I cannot click the button either. It is as if there is an invisible screen that captures every events and dismisses them all.

I've updated Xamarin to the latest version.

This is my app delegate

public override bool FinishedLaunching(UIApplication app, NSDictionary options)
        {
            InitializeDependencyFactory();
            Forms.Init();
            Window = new UIWindow(UIScreen.MainScreen.Bounds);
            LoadApplication(new App());
            return base.FinishedLaunching(app, options);
        }

Does anyone have an idea to solve this?
