Since the last update I have 2 games on steam that crash on startup. Empyrion Galactic Survival and Oxigen not Included. Both log after crash say: CSteamworks.dll caused an Access Violation (0xc0000005)
I have researched and many other games using Unity have the same exact problem.
I have managed to get Empyrion going to the main menu using this :
start Empyrion -lazyws as a .bat file.
But the game still crash giving the same error when clicking New game.
