Finally a working solution.

The problem was as @Hardcawcanary indicated. After removing the Streaming (`World Settings -> Enable Streaming = False`) and also removing all Data Layers (`Data Layers -> Select All -> Delete Selected Data layers`), the ability to Launch and Push works.

I re-added in the Data Layers and found that one of the DataLayers was corrupting things too, so I just deleted it and started that one again.

If I ever change back to Streaming - it fails. I have tried deleting the HLOD and creating a new one, but no luck. So for now I am keeping this off as it really doesnt impact my map.

Thanks all.
