Below Code is perfect working to me.

Example.xaml

ExampleConverterWithAsync.cs

public class ExampleConverterWithAsync : IValueConverter
{
    public override object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
            return new TaskNotifier(Task.run(async() => 
       {
            Task.Delay(1_000);  // replace your job
            return "Hello World";
       }));
    }

    public override object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) => Binding.DoNothing;

    public class TaskNotifier : ViewModelBase
        where T : class
    {
        private T _asyncValue;
        public T AsyncValue
        {
            get => _asyncValue;
            set { this.SetValue(ref _asyncValue, value); }
        }
        public TaskNotifier(Task valueFunc)
        {
            Task.Run(async () =>
            {
                AsyncValue = await valueFunc;
            });
        }
    }
}
