Enemies Don't Freeze When Critical Hit - [ Enchantment ]

Hello,

I am trying to make an enchantment that allows you to temporarily (5-10 ticks) stun entities and players but it doesn't seem to work. When I hit an entity (ex. Iron Golem) it doesn't stop in place. I also want blue stars and a slight vibration effect to represent the stun animation. I couldn't find a blue star particle so I used the composter one instead.

Am I doing something wrong? If so can someone help me fix it?

Here is the code:

Also an error I run into when I use ( isvanillacritical = true ) but I couldn't find anything else:
