MuseScore crashes when I try and play

I'm trying to do my music assessment and MuseScore crashes whenever I try and play it. It was working fine then I must've done something as the next moment when I tried to play it, it crashed. Any help would be greatly appreciated.

Edit: As stated it only occurred once I deleted something but I'm not exactly sure what happened. I tried copy pasting the notes into a new document but it also crashes. I'm unable to find the error. Any help would be much appreciated.

Edit 2: It appears something in the last page is causing it. Once I delete everything there it works fine.

Edit 3: Figured it out
