Describe the bug

Creating a brand new solution with the "Blank App, Packaged (WinUI3 in Desktop)" (C#) fails to launch when built in release config.

I made a repro repo here: https://github.com/jcoliz/WinUI3.Hello.

Steps to reproduce the bug

1. In Visual Studio, create a new solution using template "Blank App, Packaged (WinUI3 in Desktop)" (C#)
2. Start with Debugging (F5) on Debug X64 config (Packaged). All is well
3. Enabled mixed mode debugging
4. Start with Debugging (F5) on Release X64 config (Packaged)

Result: Unhandled exception at 0x00007FFBA70552F5 (Microsoft.ui.xaml.dll) in WinUI3.Hello.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x000001D814FC4330, 0x0000000000000002).

Debug output: Exception thrown at 0x00007FFBF082F39C (KernelBase.dll) in WinUI3.Hello.exe: WinRT originate error - 0x802B000A: 'The text associated with this error code could not be found.'.

Just for fun, I repro'd this on an Arm64 device. Same result. Interesting that the call stack is deeper.

Expected behavior

App build in release config should behave just like app build in debug config. Shouldn't crash on launch.
