Mcreator world generation stopped at 100%

So, tried to use a custom code snippet to make a specific vanilla mob to attack a modded one. However, as soon than I've joined the world, it crashed the game after a second

The same issue came in different world's as well, and even creating one

However, even deleting the procedure, it keeps making the same problem, even when making a new world

Here's the minecraft logs

The custom code snippet

((MobEntity)entity).targetSelector.addGoal(1, new NearestAttackableTargetGoal((MobEntity)entity, VillagerEntity.class, false, false));

Please, can anyone help me out to fix this?
