await Shell.Current.GoToAsync($"///MainPage"); not working

When i try to await Shell.Current.GoToAsync($"///MainPage"); I am getting System.NullReferenceException: 'Object reference not set to an instance of an object.' Microsoft.Maui.Controls.Shell.Current.get returned null.

this app.xaml.cs

c#
using MauiInvoiceApplication.Pages;

namespace MauiInvoiceApplication
{
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();

            MainPage = new NavigationPage(new LoginPage());
        }
    }
}

c#
using MauiInvoiceApplication.Pages;

namespace MauiInvoiceApplication
{
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();

            MainPage = new NavigationPage(new LoginPage());
        }
    }
