Pubsub example not working with Release 1.0.5, hangs when calling .Connect()

[Nights87]

Upon running the line _pubSub.Connect(); unity just hangs and I have to kill the editor. Running 2023.2.4f1 with HDRP pipeline.

Is there anything I need to add/do?

Code is same as the sample, but ill post anyway

private void Start()
{
  // Create new instance of PubSub Client
  _pubSub = new PubSub();
  
  // Subscribe to Events
  _pubSub.OnWhisper += OnWhisper;
  _pubSub.OnPubSubServiceConnected += OnPubSubServiceConnected;
  
  // Connect - hangs when running this
  _pubSub.Connect();
}
