How do i fix my character being frozen when i clone its body parts?

My character always freezes when i run the "else" function

local UserInputService = game:GetService("UserInputService")

local shiftKeyL = Enum.KeyCode.LeftShift
local shiftKeyR = Enum.KeyCode.RightShift

local function IsShiftKeyDown()
	return UserInputService:IsKeyDown(shiftKeyL) or UserInputService:IsKeyDown(shiftKeyR)
end

local function Input(input, gameProcessedEvent)
	if IsShiftKeyDown() then
		print("NA")
	else
		while wait(0.1) do
			local plr = game.Players.LocalPlayer
			local character = plr.Character

			local LeftArm = character["Left Arm"]:Clone()
			local RightArm = character["Right Arm"]:Clone()
			local LeftLeg = character["Left Leg"]:Clone()
			local RightLeg = character["Right Leg"]:Clone()
			local Torso = character.Torso:Clone()
			local Head = character.Head:Clone()

			LeftArm.Material = ("ForceField")
			RightArm.Material = ("ForceField")
			LeftLeg.Material = ("ForceField")
			RightArm.Material = ("ForceField")
			Torso.Material = ("ForceField")
			Head.Material = ("ForceField")

			LeftArm.Parent = game.Workspace
			RightArm.Parent = game.Workspace
			LeftLeg.Parent = game.Workspace
			RightLeg.Parent = game.Workspace
			Head.Parent = game.Workspace
			Torso.Parent = game.Workspace

			LeftArm.Position = character["Left Arm"].Position
			RightArm.Position = character["Right Arm"].Position
			LeftLeg.Position = character["Left Leg"].Position
			RightLeg.Position = character["Right Leg"].Position
			Head.Position = character.Head.Position
			Torso.Position = character.Torso.Position

			LeftArm.Orientation = character["Left Arm"].Orientation
			RightArm.Orientation = character["Right Arm"].Orientation
			LeftLeg.Orientation = character["Left Leg"].Orientation
			RightLeg.Orientation = character["Right Leg"].Orientation
			Head.Orientation = character.Head.Orientation
			Torso.Orientation = character.Torso.Orientation

			LeftArm.CanCollide = false
			RightArm.CanCollide = false
			LeftLeg.CanCollide = false
			RightLeg.CanCollide = false
			Head.CanCollide = false
			Torso.CanCollide = false

			LeftArm.Anchored = true
			RightArm.Anchored = true
			LeftLeg.Anchored = true
			RightLeg.Anchored = true
			Torso.Anchored = true
			Head.Anchored = true

			character["Left Arm"].Anchored = false
			character["Right Arm"].Anchored = false
			character["Left Leg"].Anchored = false
			character["Right Leg"].Anchored = false
			character.Torso.Anchored = false
			character.Head.Anchored = false

	end
