[1.20.1] [Forge] [Version 2.1.13 beta 5] Crash when trying to generate a hydra cave

[eternalbluepetya]

What happened?

I was simply moving around in a small radius, waiting for distant horizons to load my chunks, when my game crashed. Here is my full log output. Some additional information that might be helpful is that I tried (and thought I had succeeded considering I went hundreds of chunks only seeing one) to disable hydra caves through the config.
