The bug
A large number of mobs on a large number of turtle eggs will cause the game to crash in an uncertain time.It seems that the game thinks that the air is the turtle egg, but the data value of the turtle egg cannot be found, causing the game to crash. I've tested that 1.13 to 1.16 will crash.
It's not just creepers, many mobs and animals can cause crashes.
Any world ,even a new world,will crash.It's a low probability event that requires hundreds of mobs and turtle eggs to increase the probability.
Try this. The game will crash as soon as the commands is executed in any world
