When I test the game (on unity) it works fine. When I build the game, it flashes for a second, then the screen goes black. I still hear the music from the game, and am able to click on buttons (if I find them). I have managed to find the buttons for multiple other scenes, though the screen is the same for all.
The program ran fine before I switched it from my mac to my PC. I tried it again and the mac, the application screen flashes and stops responding. No code has been changed.
I have looked through all the of the logs, no errors have shown up. I have also looked at the similar questions and UnityAnswers, though none of them have seemed to help.
