1.18.2 LivingChangeTargetEvent NoClassDef Error

[sFXprt]

As the title states I am trying to subscribe to LivingChangeTargetEvent but it cant find the definition, I tried different annotations and that didnt work. My current annotation is 

@Mod.EventBusSubscriber(modid = Main.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD)

And this is the method I'm using

@SubscribeEvent
    public static void onTarget(LivingChangeTargetEvent e){
        LivingEntity entity = e.getEntityLiving();
        if(entity.getPersistentData().contains(XprtData.GALAXUS_SLAVE)){
            if(!entity.getLevel().isClientSide()){
                ServerLevel lvl = (ServerLevel) entity.getLevel();
                UUID id = entity.getPersistentData().getUUID(XprtData.GALAXUS_SLAVE_OWNER);
                if(lvl.getPlayerByUUID(id)!=null){
                    Player p = lvl.getPlayerByUUID(id);
                    if(e.getNewTarget().equals(p) || e.getNewTarget().getId() == p.getId()){
                        e.setCanceled(true);
                    }
                }
            }
        }
    }

this is just a simple turn any entity to do ur bidding code and I remember in past projects using LivingChangeTargetEvent and it worked. Do I have to rebuild the entire project and run mappings updates or something??

By the way I am only using my mod and optifine(removing optifine doesnt change anything) and the debug.log just says what the title says.

40.1.84 [1.18.x] Make LivingSetAttackTargetEvent compatible with the Brain/Behavior system. (#8918)

From what I understand that event was added during the above change.

The previously available LivingSetAttackTarget is currently marked as deprecated in 1.19 in favour of that new event.
