Can you provide more detailed repro steps? What sample and settings link are you referring to, and is your OS WIn10.

Hi @karkarl - Here's a screenshot. It's the latest WinUI 3 Gallery app. The Settings button is lower left, bottom of left TOC/nav.

The only thing I do after starting the app is click that Settings button, which makes the app disappear.

Windows 11 (22631.3235).

I'm also seeing the same issue, after opening the WinUI Gallery, as soon as I click the Settings menu on the Navigation, the app crashes. I'm running Win 10 Pro (Build 19045.4046)

In the cloned repo, when I run it in debug mode and click on settings, VS stops here, https://github.com/microsoft/WinUI-Gallery/blob/main/WinUIGallery/App.xaml.cs#L51C17-L51C115

Looks like .First() in windowsAppRuntimeVersion.First().FileVersion throws this.
