DocumentGroup opens an empty document on Mac Catalyst when the "Optimize for Mac" is checked

I am using a Mac Catalyst with SwiftUI for our document-based app with DocumentGroup. The issue is that when we create a new document or open an existing one, the opened view is completely blank. It is only blank/empty when the "Optimzie for Mac" is checked. If it is "Scaled t oMatch iPad", then it works well.

Xcode 16.1 macOS 15.1

struct DocumentGroupTestApp: App {
    
    var body: some Scene {
        DocumentGroup(newDocument: WritingAppDocument()) { file in
            TestView() // it is empty when it gets opened. It does not work if the option "Optimize for Mac" is checked. If it is scale iPad, then it works.
        }
    }
}

struct TestView: View {
    var body: some View {
        Text("Hello, World!")
    }
}
