[UI] [Bug] Unhandled XamlParseException at launch in release

[jcoliz]

Launches fine in debug

Debugger gives this:
Unhandled exception at 0x00007FFBA70552F5 (Microsoft.ui.xaml.dll) in LogoSlideMaker.WinUi.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x0000025DE5BFA6F0, 0x0000000000000002).

Filed an issue here: microsoft/microsoft-ui-xaml#9793

Root cause is that trimming is causing issues. Removing trimming in the sample project makes it work. Will try in main project now.
