So I went in to the end dimension in a survival world and the game crashed after a few seconds of moving, just when I was turning around. The game froze and within another few seconds it went to the "Saving World" screen. After that, the game just closed. I went back into the world and I was still where I was when it crashed. I left the end and everything was fine, but when I went back into the end, the same thing happened, again whilst turning around to face my Enderman farm. In any of the other 1.14 versions or snapshots from 19w34a to 19w46b, this didn't happen. Only in 1.15 Pre-release 1 did this happen. If this happened to anyone else, please let me know. 

It just happened again except this time I was already in the end. I did it again and the same thing happened. It just gets weirder and weirder. I may be stuck in this world where I am. Please fix this.
