Hi, I have the same issue. I actually have the apps, but I’m not able to provide answers in the App Information question. Thanks, Anton

This happened to me on iOS 17.5 (it works fine on iOS 18). What I did was simply initialize the ModelContainer in the @main struct. The odd thing that I don’t use this contaner reference anywhere, but it does fix the crash issue let container: ModelContainer? init() { do { let config = ModelConfiguration(isStoredInMemoryOnly: true) container = try ModelContainer(for: ModelName.self, configurations: config) } catch { print("Failed to initialize ModelContainer: \(error)") container = nil } } usage: WindowGroup { } .modelContainer(for: ModelName.self) // please note that it should be the @Model name, not a ModelContainer.
