Exception when calling ShowAsPopupAsync twice

Exception when calling ShowAsPopupAsync twice:

private async void CustomInputPasswdValue_OnClick(object sender, RoutedEventArgs e)
{
    ButtonDefinition[] buttons = new ButtonDefinition[2];
    buttons[0] = new ButtonDefinition() { IsDefault = true, Name = "OK" };
    buttons[1] = new ButtonDefinition() { IsCancel = true, Name = "Cancel" };
    var CustomParam = new MessageBoxCustomParams
    {
        ContentTitle = "Custom Input Passwd Value",
        ContentMessage = $"Please enter a string",
        Icon = MsBox.Avalonia.Enums.Icon.Info,
        InputParams = new InputParams() { Label = "Passwd:", DefaultValue = "AAA" }, // , PasswordChar = "*"
        ButtonDefinitions = buttons,
    };

    var box = MessageBoxManager.GetMessageBoxCustom(CustomParam);
    var result = await box.ShowAsPopupAsync(this); // Fail:On box2 ShowAsPopupAsync
    // System.InvalidOperationException:“No loaded DialogHost have an Identifier property matching dialogIdentifier ('MsBoxIdentifier4931f5a5-d63a-4814-8613-8e3870df1497') argument.”
    string InputValue = box.InputValue;
    box = null;
    if (result == "OK")
    {
       var box2 = MessageBoxManager.GetMessageBoxStandard("Caption", $"Your passwd value is:{InputValue}", ButtonEnum.Ok);
       await box2.ShowAsPopupAsync(this);
    }
}

Same as #161

I have the same error. It looks like something gets unregistered after showing dialog as popup.
