What happened is that I entered a new world to try the ally dance and it doubled, then I built a nether to see if allay really follows you to the nether and it happened I entered and the nether was intact seconds later it stopped and got me out of the game I thought the first time it was because of the bad performance of Render Dragon but this all happens Whenever you enter

The game is crashing since I entered nether with allay when I came back and found one of the portal pillars destroyed and then the game crashes and stops and exits
When I come back again it takes me back to the same place where I broke down the first time and after about five seconds it stops again and exits
