Scrolling the calendar makes the application to crash

I can't scroll the calendar view, the scroll stops at some point and makes the application to crash, also if I tab on any of the days it makes the app to crash, I have tried even only showing the calendar only in the content of the ContentPage but still the same issue.

    StackLayout mainView = new StackLayout
            {
                Padding = 0,
                Spacing = 0,
                VerticalOptions = LayoutOptions.FillAndExpand,
                HorizontalOptions = LayoutOptions.FillAndExpand,
            };

            CustomizeNavigationBar(mainView);

            _calendar = new RadCalendar
            {
                VerticalOptions = LayoutOptions.FillAndExpand,
                HorizontalOptions = LayoutOptions.FillAndExpand,
            };

            _calendar.DayNamesDisplayMode = DisplayMode.Show;
            _calendar.TryNavigateToLowerView(true);
            _calendar.WeekNumbersDisplayMode = DisplayMode.Show;

            _calendar.DisplayDateChanged += (s, e) =>
            {
                // do something  
            };

Any Ideas?
