mapItemDetailSheet Not Displaying Information

I'm on MacOS 15 Beta and Xcode 16 Beta. Running iOS 18 Beta on a 15 Pro Max. I'm leveraging the .mapItemDetailSheet(item: input) option to pull up a sheet that displays the Place Card for a selection made from a List of places.

This is working great on my iPhone 15 Pro Max and my iPad Pro 13.

I also have the Mac Catalyst option added under: Project \ General \ Supported Destinations If I launch the app from Xcode via the play button, the app functions fine on my MacBook Pro and I get logs in Xcode, etc.

However, if stop the session in Xcode and attempt to run the same app on its own on my MacBook Pro, the mapItemDetailSheet does not populate with any information.

Anyone have ideas on where the disconnect could be? Why would the sheet populate with data when ran from Xcode but not when ran on its own? Again, it runs fine on the iPhone and iPad. Any ideas would be helpful and appreciated.
