Crashing when saving after adding time signature

This has only ever been an issue with this specific score when it got to this size. Whenever I change the tempo in measure 10 and then change the time signature on that measure to 3/4 then attempt to save, it crashes every time without fail. I've sent a crash report in the past, but I also haven't seen any recent updates that would've fixed it, so I figured I'd give the forums a try. Any help would be greatly appreciated.
