Crash when trying to load a world in 1.13

When trying to load any world in 1.13, created in 1.12, downloaded from PMC, downloading it from PMC, running it in 1.12, then in 1.13, or just creating a new world, it gets stuck on Loading Terrain. Instead of trying to eat up more and more processing power like the game usually does when it crashes, my task manager shows that it is using minimal amounts of memory and CPU, as if it is not even trying to load. After about 2-3 mins, it will just crash.
