Following this advice, I was able to boot the game and load into the world, only to have it crash again with a debug log that is 9,302KB in size. I then restarted the game, and it worked without crashing for about 10 minutes now, which is a massive win. I don't know why it works, or why it crashed, but I imagine this is what being a programmer is like, in any case, my initial issue is solved.
