Binding ScheduleView leads to error on Android

Hello,

i'm trying to use a binding for ScheduleView in my Xamarin.Forms app using Prism.

On loading my page i set set ScheduleView to WeekView in my Viewmodel 

This used to work in Version 16.1.0.37 but after updating to 16.4.0.48 when i hit the BackButton on Android i get this error message and my app crashes:
