Game crashes when approaching new structures

Hello, I am currently experiencing a problem when testing the snapshot version 18w48a. I did not try the previous versions, I do not know if it was already the case. When I go to a new world, I make / locate New_Village to see what the villages look like, but the game instantly starts to crash. I tried to move to the coordinates of the new village (by launching a new world) but nothing to do, within a radius of 300 blocks or so the problem starts again. I noticed that the game also crashes for the Pillager_Outpost, so I deduce that the problem could come from the new generation of the field.

Thank you for the attention to my message,
