I have a problem with a MacCatalyst app I build and run on MacOS 14.6 with XCode 16.4. The problem doesn’t occur on MacOS 13.6 or iOS 16 or 17. In this app if I click a button to show a .sheet(item a few times (typically between 3 and 8 times) then the app starts consuming 100% CPU and the Spinning Wait Cursor shows. The cause of the issue is that my NavigationSplitView has a ZStack so that state is maintained for all panels, as recommended here and here. Minimum reproducible example is below. I would appreciate any suggestions on how to address this. This app must support iOS 16 and MacOS 13.6 as well. Thank you!

I have a NavigationSplitView and router for navigation with code.
