FileOpenPicker.PickSingleFileAsync() Causes a crash when app is started from an elevated context/tarted as Adminitrator

[mide25]

Describe the bug

When a WIN UI 3 app is configured to start with elevated privileges by adding the allowElevation capability and setting the requestedExecutionLevel to requireAdministrator; invoking FileOpenPicker.PickSingleFileAsync() causes the application to crash (note: this is irrespective of IDE as it also crashes when I run outside of Visual Studio). On further investigation wrapping FileOpenPicker.PickSingleFileAsync() and logging the exception to a file gives the following error:

Error HRESULT E_FAIL has been returned from a call to a COM component.
System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.

Checking the Event viewer logs shows:

Faulting module name: CoreMessagingXP.dll, version: 10.0.22621.1003, time stamp: 0xc93a5eeb
Exception code: 0xc000027b
Fault offset: 0x0000000000090e1c

Steps to reproduce the bug

Go to your application's Package.appxmanifest and add the capabilities:

<Capabilities>
    <rescap:Capability Name="runFullTrust" />
	<rescap:Capability Name="allowElevation"/>
  </Capabilities>

Go to the application's app.manifest and modify as follows:

<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
	<security>
		<requestedPrivileges>
			<requestedExecutionLevel level="requireAdministrator"/>
		</requestedPrivileges>
	</security>
  </trustInfo>

Ensure your application has a button that triggers a FileOpenDialog. See sample below:

FileOpenPicker open = new FileOpenPicker();
InitializeWithWindow.Initialize(open, MainWindowPtr); //MainWindowPtr is the pointer to the main window of the app (i.e. parent of the current page that extends Window). This line attaches the dialog to the window of your app.
open.SuggestedStartLocation = PickerLocationId.ComputerFolder;
open.FileTypeFilter.Add(".exe");
StorageFile file = await open.PickSingleFileAsync();

Note that the app crashes/throws a COM exception

Expected behavior

It should pop up the select file/folder dialog even when the app is started with administrator privileges
