I'm late, but there seems to be a recurring issue with the Movies in general not loading. I think all you can do is close out and play again from the beginning. I had this exact same issue. If you really want to play to the ending, I would recommend using the Game Guide in the Files of the game. You probably already know to use it since you know that your ending is the good one, but just in case, the Readme has instructions on how to get there. If you need more clarification then feel free to ask.
I plan on retrying to play for the Good Ending again (since it lagged the first time like I said) so I guess I'll tell you how it goes or if I find a way to fix it if it freezes again.
