Hello Marco,
From the stack trace it looks like that some VisualState is trying to access an UIElement with name Content, but such UIElement is missing. I would like to ask you if you could give us some code snippets so that we could help you better (the custom SplitButton template that you use will be very useful)?

Best wishes,
