V2 update for popup

[TheR7angelo]

using CommunityToolkit.Maui.Extensions;
using Serilog;

namespace MyExpenses.Smartphones.ContentPages.CustomPopups.CustomPopupActivityIndicator;

public static class CustomPopupActivityIndicatorHelper
{
    private static CustomPopupActivityIndicator? _customPopupActivityIndicator;
    private static bool _isOpen;

    public static void ShowCustomPopupActivityIndicator(this Page contentPage, string messageToDisplay)
    {
        _customPopupActivityIndicator = new CustomPopupActivityIndicator { LabelTextToDisplay = messageToDisplay };
        _customPopupActivityIndicator.Opened += CustomPopupActivityIndicatorOnOpened;
        _customPopupActivityIndicator.Closed += CustomPopupActivityIndicatorOnClosed;
        contentPage.ShowPopup(_customPopupActivityIndicator);
    }

    private static void CustomPopupActivityIndicatorOnClosed(object? sender, EventArgs e)
    {
        Log.Information("CustomPopupActivityIndicator closed");
        _isOpen = false;
    }

    private static void CustomPopupActivityIndicatorOnOpened(object? sender, EventArgs e)
    {
        Log.Information("CustomPopupActivityIndicator opened");
        _isOpen = true;
    }

    public static void CloseCustomPopupActivityIndicator()
    {
        Log.Information("CustomPopupActivityIndicator close requested");
        _customPopupActivityIndicator?.CloseAsync();
    }
}

In Popup V1 I used this code to open a popup to say a waiting message to the user and after a load I close the popup but in V2 the popup opens too late and the close request does nothing.
If I click outside the popup to close it manually, my application crashes saying there is no popup open.

Can you help me understand what the problem is, whether it's my code or a V2 bug?
