From my experience no error message showed for me. what would happen would be that I would be playing the game and then all of a sudden the game would freeze. My first experience with this was when I was listening to the phonograph, I could still hear the games sounds but the text froze and wouldn't continue, this also happened to me after I exited the room where Zakhari was and when it was time for the cutscene the whole screen went black. I could still hear the sounds of when I try to access the menu but the game wouldn't actually respond and none of the buttons would work. If I quit off the game and then load back to my save the game usually worked the second time though. Actually on one instance I believe I had a error message saying unknown error but the other times the game kind of just froze. Sorry I couldn't help with the crashing issue more.
