Xamarin.Forms UWP application crashes on start

I built a Xamarin.Forms app. When I run the UWP version, it works on simulator, but when I install it on my Windows 10 machine from AppCenter, it crashes after splash screen. The same thing happens on a Surface tablet. iOS and Android both work fine. Here is what I see in the Event Viewer:

Any idea on what could cause this?
