Why is my ScreenGui not visible? I didn't make a StarterGui to PlayerGui error?

As the title states my problem, why so does it not show? The camera moves to a specific location in my shop script but, it does not show the interacting GUIs.

game.ReplicatedStorage.eventFolder.cameraEvent.OnClientEvent:Connect(function()

local player = game.Players.LocalPlayer

local shop = player.PlayerGui.shopGui

local camera = workspace.CurrentCamera

local shopmodel = workspace.shopModel

local item = shop.itemValue

local buy = shop.shopFrame.buyButton

local shadow = buy.shadowButton

if shop.closedValue.Value == false then

if shop.openValue.Value == false then

shop.openValue.Value = true

buy:TweenPosition(UDim2.new(0,0,0,0), "Out", "Quint", 1,true)

item.Value = 1

camera.CameraType = Enum.CameraType.Scriptable

camera.CameraSubject = shopmodel.camera1Part

camera.CFrame = shopmodel.camera1Part.CFrame

shop.shopFrame.textLabel.Text = shopmodel:FindFirstChild("info"..item.Value.."Part").itemName.Value

buy.Text = shopmodel:FindFirstChild("info"..item.Value.."Part").itemPrice.Value

game.StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false)

if player.Backpack:FindFirstChild(workspace.shopModel:FindFirstChild("info"..item.Value.."Part").itemName.Value) ~= nil then

buy.Text = "Bought"

buy.BackgroundColor3 = Color3.new(0.7, 0.7, 0.7)

shadow.BackgroundColor3 = Color3.new(0.5, 0.5, 0.5)

else

buy.Text = workspace.shopModel:FindFirstChild("info"..item.Value.."Part").itemPrice.Value

buy.BackgroundColor3 = Color3.fromRGB(85, 255,127)

buy.BackgroundColor3 = Color3.fromRGB(70, 212, 104)

end

end

end

end)

The code didn't let me make it a code-block.
