ProtocolLib v4.8.0 doesn't support 1.19.4. Update ProtocolLib to at least v5.0.0.

im using this:

public final boolean hideEntity(Player observer, Entity entity) {
        validate(observer, entity);
        boolean visibleBefore = setVisibility(observer, entity.getEntityId(), false);

        if (visibleBefore) {
            PacketContainer destroyEntity = new PacketContainer(ENTITY_DESTROY);
            destroyEntity.getIntegerArrays().write(0, new int[] { entity.getEntityId() });

            // Make the entity disappear
            try {
                manager.sendServerPacket(observer, destroyEntity);
            } catch (InvocationTargetException e) {
                throw new RuntimeException("Cannot send server packet.", e);
            }
        }
        return visibleBefore;
    }
