why Inferred type 'I' for type parameter 'I' is not within its bound; should extend 'net.minecraft.potion.Effect'.

public static final DeferredRegister<Effect> EFFECTS = DeferredRegister.create(ForgeRegistries.POTIONS, Utils.MOD_ID); 

public static final RegistryObject<Effect> bl_instinct = EFFECTS.register("bl_instinct", BLInstinct::new);

register requires a supplier for the registry type (in your case Effect). You are giving it a constructor reference that does not match up with the functional interface Supplier. If you don't know what constructor/method references, lambdas and functional interfaces are - look them up. Or don't use them, you can implement the interface normally, too.

@SubscribeEvent

public static void onPotionRegistration(RegistryEvent.Register<Effect> event) {

event.getRegistry().registerAll(new BLInstinct(EffectType.NEUTRAL,0x993333).addAttributeModifier(Attributes.MAX_HEALTH,"7107DE5E-7CE8-4030-940E-514C1F160890",0.5f, AttributeModifier.Operation.MULTIPLY_TOTAL).setRegistryName(Utils.MOD_ID, "bl_instinct"));

}

This way no erro,but there is no effect in game.
