"Solution" ?

Hello, In my case it happens when I close the session with masterdetailpage, to solve it we have to close the menu with IsPresented and leave a waiting time to perform the navigation.

Example with PRISM MVVM and MessagingCenter.

MasterPageViewModel.cs (Method)

private async void Logout() 
{
     MessagingCenter.Send(this, "Logout");
     await Task.Delay(500);
              
     // Navigation Login
     await this.NavigationService.NavigateAsync(new Uri("/LoginPage", UriKind.Absolute));
}

MasterPage.xaml.cs

namespace ProjectXamarin.Views
{
    using ProjectXamarin.ViewModels;
    using Xamarin.Forms;

    public partial class MasterPage : MasterDetailPage
    {
        public MasterPage()
        {
            InitializeComponent();

            // Close Menu
            MessagingCenter.Unsubscribe<MasterPageViewModel>(this, "Logout");
            MessagingCenter.Subscribe<MasterPageViewModel>(this, "Logout", (sender) =>
            {
                this.CloseMenu();
            });
        }

        private void CloseMenu() 
        {
            this.IsPresented = false;
        }
    }
}

Sorry my English (Google translator).

I confirmed that stivenbr's solution worked for me. I'm build an app using the Prism framework. So my changes went into one file, the view model class.

MasterDetailPageViewModel.cs

private async Task ItemTappedAsync(MasterDetailPageMenuItem menuItem)
{
        // If the user is logging out, navigate to the LoginPage and make it the main page.
        if (menuItem.Title == Constants.LogoutPage)
        {
                await NavigationService.GoBackToRootAsync();
                // Prevent unhandled exception, System.ObjectDisposedException, on object, KeyboardOverlapRenderer.
                MasterDetailPage1 page = (App.Current.MainPage as MasterDetailPage1);
                if (page != null)
                {
                        page.IsPresented = false;                        
                }
                // Relinquish control to the UI thread
                await Task.Delay(500);
                // Now navigate to the LoginPage
                await NavigationService.NavigateAsync(Constants.LoginPageUri);
                return;
        }
}
