I just added a ComboBox, also tested it in pretty clean (?!) test project (https://github.com/yki5000/WinUI3_Unpackaged_CPP).
The linked app is just the example for a simple unpackaged app. The test of the other ComboBox is not contained but i used this app for testing.
<ComboBox x:Name="cmbApplication" Width="250" CornerRadius="3">
<ComboBoxItem Foreground="Gray" >eeee</ComboBoxItem>
</ComboBox>

Anonymous2022-12-26T03:48:23.243+00:00 I could reproduce this behavior in a blank CPP Winui3 application. I've also noticed that this behavior has already been reported before: Combox Errors in KernelBase.dll--> WinRT Transform error. It seems to be a first chance exception which you could ignore. I'll discuss this behavior with the team later. Thank you for your patience in advance.
