System.Runtime.InteropServices.COMException: 'No installed components were detected

Question

Context: We have recently ported an old Xamarin.Forms project into .NET MAUI. We now have the app opening and a working login. The Main Page after logging in is a page where users can log their actions. Currently, if I have a log from the previous day and click an arrow on the page to go see it, I recieved the No Installed Components Detected issue on my SETMODELBINDING method, which is the last method listed below. The following is redacted code:

public DailyLogPage(int dailylogid = 0)
{
    dlog = new DailyLogControl();
    myid = Guid.NewGuid();
    loadingControl = new LoadingControl();
    this.Title = "Daily Log";
    IconImageSource = "Navigation_Add.png";
    this.Disappearing += MainViewPage_Disappearing;
    BasePage.InitPage(this);

    SetDataRepository();
    InitializeCriteria();
    CreateDailyLogUI();
    CreatePageActions();
    SetMessagingCenterSubscriptions();
    SetHomeOpco();
    AutoSaveAndSync();
}

#region UICode
private void CreateDailyLogUI()
{
    CreateTxtDevice();
    CreateGrid();
    CreateMainScrollView();

    stackBody.SetBinding(StackLayout.BackgroundColorProperty, "PageColor.BodyBackground");
    this.SetBinding(ContentPage.BackgroundColorProperty, "PageColor.PageBackground");
    SetModelBinding(dailylogCriteria.DailyLog);
}

private void CreateTxtDevice()
{
    txtDevice = new AutoCompleteView
    {
        Placeholder = "Enter text",
        ShowSearchButton = false,
        SuggestionsHeightRequest = 120,
        SelectedCommand = new Command(() => { }),
    };
    txtDevice.EntText.IsVisible = false;
}

private void CreateGrid()
{
    AddButton = new Button
    {
        HeightRequest = 45,
        ImageSource = "add_data.png",
        BackgroundColor = Colors.Transparent
    };
    AddButton.Clicked += AddButton_Clicked;

    sideStack = new StackLayout();
    grid = new Grid

Answer 1

System.Runtime.InteropServices.COMException: 'No installed components were >detected

stackmain.Children.Insert(0, dlog);   <---- THIS IS WHERE THE ERROR OCCURS

About this, I find an issue on MAUI GitHub: [Windows] Faced no installed components were detected exception #8997, you can try the solution mattleibow provided:

I think it may be because you are adding a child during a layout cycle? >Maybe you can avoid this by adding via a dispatch. This should cause the >child to be added after the layout is complete:

this.Owner.Dispatcher.Dispatch(() => this.Owner.Children.Add(myLabel));

Hope it can help you.
