I'm developing an app with a chart in SwiftUI. I want the following block of code to run when the chart is clicked. On my personal iPhone, the app works flawlessly. But when I try it in the simulator it crashes and gives me about 5-10 of the following errors. When I remove the @Query macro from the code block, the application does not crash in the simulator, but I continue to get the errors I mentioned. If I do not run the following code block, I do not get the errors I mentioned.

struct SaleDetailView: View {
    
    @Query(filter: #Predicate<Registration> {
        !$0.activeRegistration
    }) private var regs: [Registration]
    
    var body: some View {
        VStack {
            DailySaleView()
        }
        .padding()
    }
}

When trying the app on my personal iPhone, cpu usage is max 50%. However, when I try it in the simulator, when I open the chart screen, it goes above 100% and goes back down to 0. If you stop the app in the meantime, you get the errors I mentioned. If you stop the application after the cpu usage drops to 0, you do not get any error. Is this a normal situation?
