Hi guys,

new here, I got the following error last week and wanted to open the discussion, not sure where this error happened. Do you have any idea/suggestions on how to handle this? Here is the call stack:

Type: System.InvalidCastException Message: Unable to cast object of type 'ListItem' to type 'System.Collections.Hashtable'. Source: PresentationCore HelpLink: TargetSite: ListItem getLayoutUpdatedHandler(System.EventHandler) StackTrace: at System.Windows.UIElement.getLayoutUpdatedHandler(EventHandler d) at System.Windows.UIElement.remove_LayoutUpdated(EventHandler value) at Caliburn.Micro.View.<>c__DisplayClass10_0.b__0(Object s, EventArgs e) in D:\a\1\s\src\Caliburn.Micro.Platform\View.cs:line 202 at System.Windows.ContextLayoutManager.fireLayoutUpdateEvent() at System.Windows.ContextLayoutManager.UpdateLayout() at System.Windows.ContextLayoutManager.UpdateLayoutCallback(Object arg) at System.Windows.Media.MediaContext.FireInvokeOnRenderCallbacks() at System.Windows.Media.MediaContext.RenderMessageHandlerCore(Object resizedCompositionTarget) at System.Windows.Media.MediaContext.RenderMessageHandler(Object resizedCompositionTarget) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

Tell me if you need more information to understand the issue. Have a good day
