This is a known issue with NavigationView in SwiftUI. In my app i resolved the using the following trick:
struct ContentView: View {
		
	@Environment(\.presentationMode) var presentation
		
		var body: some View {
				NavigationView {
		}
	}
}
That triggered the correct presentation mode for me and resolves the issue where the navigation buttons become unresponsive.
