lag when instantiating curvy spline prefab on android

[Zik Dipa]

I made a feature where players can make axis straps, each axis that is installed requires a curvy spline on the object, when the player attaches the axis there will be a lag once when the object is installed then the lag is no longer, the problem is when the player installs again the axis will occur again in the game.

if the prefab that will be instantiated by the player does not have a curvy spline, lag will not occur.

I'm confused about how to solve this problem because if the prefab I want to instantiate doesn't have a curvy spline then the prefab doesn't work.
