Nether Crashes upon Generation

In my survival world that I just created, I managed to get 10 obsidian and go to the nether. However, once I was supposed to be sent to the nether, the game crashed. Here is my crash report: https://pastebin.com/g9yCQQ9y

I'm sorry if this is a duplicate; I searched and couldn't find this same issue.

I'm not using any mods. Also, when I load the world again, it doesn't crash, I'm instead just sitting in the portal in the overworld.

Thanks in advance!
