Is there a reason this renderstepped is crashing studio?

Basically im using renderstepped to clone the character, and then remove anything other than parts. It then moves it to the position in which the player's character torso just left. Here is my code

run:BindToRenderStep("Gengeki",1,function()
                    print("hi")
                     local fake = player.Character:Clone()
                    for i,item in pairs(fake:GetChildren()) do
                        if item:IsA("Part") then
                            item.Transparency = .5
                            item.CanCollide = false
                        else
                            item:Destroy()
                        end
                    end
                    local cval = Instance.new("CFrameValue")
                    cval.Value = player.Character.Torso.CFrame
                    fake.Torso.Anchored = true
                    fake.Parent = game.Workspace.TempStorage
                    fake.Torso.CFrame = cval.Value
                    -- Where "from", where "to"
                    local inRoot = player.Character.HumanoidRootPart.CFrame
                    local outRoot = fake.HumanoidRootPart.CFrame
                    for _, part in pairs(fake:GetChildren()) do
    if part:IsA("BasePart") then
        -- Get original part relative to character:
        local correspond = player.Character[ part.Name ].CFrame
        -- Move me relative to my root:
        part.CFrame = outRoot * inRoot:toObjectSpace(correspond)

        end
    end
end)

        for i,v in pairs(game.Workspace.TempStorage:GetChildren()) do

    v:Destroy()
    wait()
end
repeat wait() until script.Parent.Parent.Gengeki.Value == false
run:UnbindFromRenderStep("Gengeki") 

Any advice helps, thanks
