I'm so sorry this had to be my first post here.
I posted this on the Steam discussions after doing everything Steam suggested for fixing the game and after talking to my dad he says that the issue I'm having is a bug. I've had it for two routes, the first one starts right when I'm about to start the epilogue for siding with Golgotha as a Iscari. I'll get to the final test before the screen blacks out and rather than starting the epilogue looking out at the city, a white error exception occurred screen pops up. This is what happens in my other route where I'm replaying Randal's route as a Isacri trying to take over LA and romance him. The second error occurs on the roof after the talk about celebrities and he's about to respond.
I've got the tracebacks for both and screenshots of the error message saved still if needed. I really love the game and want to keep playing it but I don't know if more issues are going to arise if I do. I still don't know why this is happening now since my game is up to date with the last patch.
