Anycubic Next Slicer / Kobra S1 Combo / Windows - No Home Screen or Workbench on the application

Hi all, I'm having issues with my Slicer Next. I cannot see a Home Screen or a Workbench. I can send files to the printer remotely and the iphone app works but the actual slicer software doesn't appear to be working properly.

Any helpful suggestions greatly appreciated.
