[MC-136754] 1.13 crashing. 1.12 now gets stuck creating new world

I tried to update a 1.12 world to 1.13. Now, I can't load 1.13 at all. Crashes on Start. Switching back to 1.12, it gets stuck loading and creating new worlds. The dirt window opens and stays there indefinitely. It becomes unresponsive, and I have to force quit.

Edit: I've also deleted my entire ~/Library/Application Support/minecraft folder a few times to reset things. It seemed to help, but I tried to reopen a game, and it started crashing again.
