I can't update the character if they change in-game through player viewport frame

I can’t seem to update a character appearance in the viewport frame when they change their avatar in-game. Any help would be greatly appreciated.

local script

-- Variables
local uis = game:GetService("UserInputService")

local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()

local MouseInDisplay, HoldInDisplay = false, false

local currentX

-- Character Display
local VPFcam = Instance.new("Camera"); VPFcam.Parent = script.Parent.ViewportFrame
VPFcam.CFrame = CFrame.new(0,0,0)
script.Parent.ViewportFrame.CurrentCamera = VPFcam

repeat wait(.1) until game:IsLoaded()

char.Archivable = true

local ClonedChar = char:Clone()

ClonedChar.Parent = script.Parent.ViewportFrame.WorldModel
ClonedChar.Humanoid.DisplayDistanceType = Enum.HumanoidDisplayDistanceType.None
ClonedChar:SetPrimaryPartCFrame(CFrame.new(Vector3.new(0,0,-9.5),Vector3.new(0,0,0)))

-- Turning Feature
uis.InputBegan:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		if MouseInDisplay == true then
			HoldInDisplay = true
			currentX = nil
		end
	end
end)

uis.InputEnded:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseButton1 or input.UserInputType == Enum.UserInputType.Touch then
		HoldInDisplay = false
	end
end)

script.Parent.ViewportFrame.MouseMoved:Connect(function(X,Y)

	if HoldInDisplay == false then return end

	if currentX then ClonedChar.PrimaryPart.CFrame *= CFrame.fromEulerAnglesXYZ(0,((X-currentX)*.025),0) end

	currentX = X
end)

script.Parent.ViewportFrame.MouseEnter:Connect(function() MouseInDisplay = true end)
script.Parent.ViewportFrame.MouseLeave:Connect(function() MouseInDisplay = false end)
