Whenever i add the this.getEntityAttribute(SharedMonsterAttributes.ATTACK_DAMAGE).setBaseValue(3.0D); to my custom entity it causes the entity to not be able to be spawned, but the entity spawns and loads properly whenever i don't have the attribute if anyone can help me it would be greatly appreciated.

You can't do this in the entity constructor since models are client-side and this will crash the server.

EntityCreature doesn't have ATTACK_DAMAGE registered at all, hence the NPE when getting it. You need to register the attribute first with AbstractAttributeMap#registerAttribute. See EntityMob for an example.

This task only selects the nearest entity matching the predicate as a target. It doesn't actually make the entity move to the target or even attack it. You need to add those other tasks too.
