NavigationView gives an exception when it's the only thing on the page

0

I'm using the new Project Reunion 0.5/WinUI3 Preview 5. And after my upgrade from Preview 4, I started to get this error:

Exception thrown at 0x76C5A8B2 in ReunionTest.exe: Microsoft C++ exception: winrt::hresult_error at memory location 0x00D7E290.

The Output shows:

Exception thrown at 0x76C5A8B2 (KernelBase.dll) in ReunionTest.exe: 0x40080202: WinRT transform error (parameters: 0x8000000B, 0x80070490, 0x00000014, 0x00D7BCCC).

This all the XAML.

Add the two SolidColorBrushs and oddly it should stop crashing when you run Debug.
