How would I make this "insert SpecialMesh in a HumanoidRootPart" compatible with FilteringEnabled?

In a LocalScript located in StarterCharacterScripts.

Works perfectly fine in Studio Play mode but will not work in-game.

player = game.Players.LocalPlayer
local character = player.Character
character.HumanoidRootPart.Transparency = 0
MeshInsert = Instance.new("SpecialMesh", character.HumanoidRootPart)
