Frequent random crashes in packaged game

I finally managed to get my game to package successfully, only to find that the packaged game always crashes at some point during play, and always at a random time. Sometimes it’ll crash 2 seconds in, sometimes ten minutes in, and there’s no log to check to find out why. It’s very aggravating, and the packaging output log isn’t giving any clues either. If someone knows a good place for me to start, it’ll be appreciated.

I’ve obtained a log from the most recent crash for reference. Any help would be appreciated. link

Did you ever find a fix to this? I’m having the same problem.
