0xC000027B exception in store UWP app (Windows.UI.XAML)

I've an C#/UWP-app in beta-release in the Microsoft App-Store. Most of the users have no problems with the App, but for one user the app is crashing on startup. You can't even see the Splash-Screen (it should be displaying a logo or color, however it is white).

In the eventlog this genreic event is logged:

0xc000027b (Windows.UI.XAML)

The only difference is, that his Windows-10 Build differs from the other users (10.0.10240 vs 10.0.10586). However, I've collected the crashdumps ("minidumps") and tried to follow this tutorial. If i try this command:

dt <Parameter[0]> combase!_STOWED_EXCEPTION_INFORMATION_HEADER*

Windbg gives me this:

Memory read error (at Parameter[0])

Actually I've integrated the hockey-sdk for automatic crash-reports, but it doesn't report me that specific crash in the dashboard.

How can I trace down this crash?

This would mean, that I've somewhere an incorrect binding?
