This Script Works in Studio But Not in The Actual ROBLOX Game How do I Make it Sever Side?

script.Parent.Humanoid:SetStateEnabled("RunningNoPhysics", false)

So this script stops my custom character from falling through the map. It works great, but only in Studio. The minute I play the published version of the game he falls through the map again.

I tried using both local and a normal script but the both failed at success.

The script is located under the StarterCharacter.
