I have uploaded the file.
After reporting the problem I started to wonder if it was my PC as it is a bit old so my wife installed AP on her much newer laptop instead but the same problem occurred.

Even just scrolling through the pages of the file caused it to crash seemingly at random. We have gone back to trying the PC and we can eventually get it to load up without crashing on that as well but it still crashes on that oc
