Weird movement after using an attack with welding

[Envious_Soul (Env1)]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I’m trying to understand why my character moves weirdly and jitters after using a skill with welding.
2. What is the issue? Include screenshots / videos if possible!

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   I’ve already tried turning the model’s massless property on, changing rootpriorities, and parenting the model outside of the character.

Are you creating any other parts? Could you show me the code you use to create the visual effects?

I only had attachments and meshes that are parented in a folder in the workspace for my visual effects.
