Выполнение метода прерывается на строке

Question

Выполнение метода останавливается на определенной строке, дальше не идет (причем, выполнение подобного метода в другом классе успешно).

public partial class ChatFormViewModel : BaseViewModel, IQueryAttributable
{
    public void ApplyQueryAttributes(IDictionary<string, object> query)
    {
        Dialog = query["Dialog"] as Models.Dialog;
    }
Command ShowProfile { get; set; }
Timer _timer;
Models.Dialog dialog;

public Models.Dialog Dialog
{
    get {
        Console.WriteLine($&quot;dialog.title: {dialog.Title}&quot;);
        return dialog; }
    set
    {
        dialog = value;
        OnPropertyChanged();
    }
}

public Command SendMessage { get; private set; }



private ObservableCollection&lt;MessageInChat&gt; _messages = new();
public bool isBackButtonVisible;
private string _newMessageText =&quot;&quot;;


public ObservableCollection&lt;MessageInChat&gt; Messages
{
    get =&gt; _messages;
    set
    {
        if (value != _messages)
        {
            _messages = value;
            OnPropertyChanged();
        }
    }
}

public string NewMessageText
{   
    get =&gt; _newMessageText;
    set
    {
        _newMessageText = value;
        OnPropertyChanged(nameof(NewMessageText));
    }
}


async Task UploadMessages() //проблема в этом методе
{

            List&lt;Models.Message&gt; list = server.GetDialog(dialog.DialogID); //предполагаю, что проблема в выполнении этого
            Console.WriteLine(&quot;Upload is running4&quot;); //этой и последующих строк в консоли нет
            Console.WriteLine($&quot;[Messages] List length: {list.Count}&quot;);
            foreach (var item in list)
            {
                MessageInChat message = new()
                {
                    SenderID = item.userId,
                    ID = item.messageId,
                    Message = item.message,

                    MessageFrom = item.messageFrom,
                    timeSended = TimeToString(item.sendedAt),

                    GridColumnMessage = item.messageFrom ==
                        Constants.Server.MESSAGE_FROM_ANOTHER ? 1 : 0,
                    GridColumnImage = item.messageFrom ==
                        Constants.Server.MESSAGE_FROM_ANOTHER ? 0 : 1,
                    statusImage = getStatusImageResourceByMessageStatus(item.status),
                    HorizontalOption = item.messageFrom ==
                        Constants.Server.MESSAGE_FROM_ANOTHER ? &quot;start&quot; : &quot;end&quot;,
                    Background = item.messageFrom == Constants.Server.MESSAGE_FROM_ANOTHER ?

                };
                _messages.Add(message);
            }

    }
}

async Task init()
{
    Console.WriteLine(&quot;Checker init&quot;);
    if (server.IsHasNewMessages()) await UploadMessages(); // IsHasNew Messages возвращает false


}

Task Init { get; set; }

public ChatFormViewModel()
{
    Console.WriteLine(&quot;init viewmodel&quot;);

    _timer = new Timer(new TimerCallback(async (s) =&gt; await init()),
                  null, TimeSpan.Zero, TimeSpan.FromMilliseconds(300));
    Init = UploadMessages();
}

~ChatFormViewModel() =&gt; _timer.Dispose();

...}

GetDialog метод:

 public List<Models.Message> GetDialog(int dialogID)
    {
        Console.WriteLine("Method init"); //этой строки так же нет в консоли
        List<Models.Message> MsgList = new();
    MsgList.Add(new Models.Message()
    {
        userId = 0,
        messageId = 0,
        userName = &quot;Даниил&quot;,
        imageResource = &quot;user_no_image.png&quot;,
        message = &quot;Lorem ipsum dolor sit amet&quot;,
        messageFrom = Constants.Server.MESSAGE_FROM_ANOTHER,
        status = Constants.Server.MESSAGE_STATUS_NOTREADED,
        sendedAt = DateTime.Now,
    });

    MsgList.Add(new Models.Message()
    {
        userId = 0,
        messageId = 0,
        userName = &quot;Даниил&quot;,
        imageResource = &quot;user_no_image.png&quot;,
        message = &quot;Lorem ipsum dolor sit amet&quot;,
        messageFrom = Constants.Server.MESSAGE_FROM_CURRENT,
        status = Constants.Server.MESSAGE_STATUS_NOTREADED,
        sendedAt = DateTime.Now,
    });

    return MsgList;

}
