Hmmm, 2018 isn't that old. Do you happen to know the specs of it? How much RAM, what CPU?
I don't THINK that's it, but it's hard to really say what it might be for me unfortunately, and 2018 PC parts should be able to handle it.
It's really strange that it crashes on three different devices in what sounds like the same manner. Or well, phone and tablet crashes in the same manner, but then the PC runs through most of the game before crashing? Just strange. There shouldn't be anything new introduced that late or in that scene that would cause it.
Does it load other saves (if there are any) on the PC, or start a new game?
