Bug: Game crashes at final story fight

After you beat the first part of the final battle there is a cutscene where the screen fades to red/maroon and at this point my game froze, several attempts in a row.

I was originally in fullscreen, and I only managed to get past this part by switching to windowed mode and turning on “high performance mode” (which screwed up the graphics but it seemed like it helped, not sure if all I had to do was switch to windowed because I tested both at once) but then I had to fight the final story battle with glitched out graphics.

This is on a MacBook Pro M1 2020.
