If your game freezes at the 222 mark during the 2015 west part, it means you haven't used the Explorers Kit before; in that area, the game makes you go through the Underground, but since you haven't done it yet, it tries to load the tutorial, but crashes because it can't since you're in the void. To fix it, get use the Explorers Kit, go though the tutorial, and it should fix it.

If this doesn't work(or you've already done the Explorers Kit and this is still happening, then idk what's going wrong. You may have to start over a new file or something.
Hope this helped you! I've done the void glitch lots of times and I never had this problem cuz I've already used the Explorers Kit before hand(and cuz YouTube tells you that you need to use it). Hope your problem is resolved! :)
