Ok, I just figured something out. When I received the error today, I could still see the cutscene playing in windowed mode. A cutscene I previously couldn't access without a crash was going through the lines as I set it to auto-advance. It went through the entire cutscene and the game loaded to the next area without an issue but the error message prevented me from bringing focus to the actual game. I couldn't dismiss the error without actually closing the game either. I can at least try to brute force some of these cutscenes to completion hopefully to get to Shadowbringers content and see if my issue persists.
