VFX

enable Read/Write on your character’s mesh and click apply, as shown in the screenshot. I believe this is the issue.

Drag one of the VFX Dash Controller script from the Scripts/VFX Dashes folder onto your character.

Create a GameObject and attach the VFXEffect script from the Scripts/Effects/ folder to it.

Add a VFX Graph to the GameObject (demo effects are in the Effects/Visual Effects/ folder).

Create a Property Binder and assign your character to it.

Assign the SkinnedMeshRenderer if required.

Assign your GameObject in the VFX Dash Controller component.
