Hello,
When I launch through steam and click “Create Lobby” I just get a black screen, nothing happens. When I test in the Unity editor it pulls up my lobby screen as it should and properly displays Player 1. The error only happens on Steam.
After looking through my code I could not find an answer so I tried replacing my code with the GitHub commit for the Menu script and I still have the same issue. The issue is not the Network Manager being setup incorrectly as seen in picture below. I added a second picture to show my Lobby working in the editor vs what I get when launching through Steam.!
