I think you will be disappointed with the screenshot inasmuch as the crash is very quick, quicker than my screenshot.
This is not straightforward. My implementation of MuPDF, for some reason, is not able to read your file. Unfortunately, your PDF worked fine on my PC (both 32 and 64 bit). I'd like to take this off-forum and work it with you. Can you please check your private messages?
