Nullability of reference types in return type of 'T? AsyncBlockingQueueEnumerator.Current.get' doesn't match implicitly implemented member 'T IAsyncEnumerator<T>.Current.get' (possibly because of nullability attributes).

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.
