Why isn't this spawning?

I'm trying to make a shield, and when you press t a part is supposed to spawn 1 stud in front of you, but instead it doesn't spawn at all and returns this error: bad argument #3 to CFrame (CFrame expected, got Vector3)

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local chr = plr.Character or plr.CharacterAdded:wait()

local shield = Instance.new("Part")
shield.Anchored = true
shield.Transparency = .8
shield.CanCollide = false
shield.FormFactor = "Custom"
shield.Size = Vector3.new(.2,.2,.2)
shield.BottomSurface = "Smooth"
shield.TopSurface = "Smooth"

mouse.KeyDown:connect(function(key)
	if key == 't' then
		chr.Humanoid.WalkSpeed = 0
		clone = shield:Clone()
		clone.Parent = workspace
		clone.CFrame = chr.Torso.CFrame.lookVector*10
		
		clone.Touched:connect(function(p)
			if p and p.Locked == false then
				p:Destroy()
			end
		end)
		for i = 1,25 do
			game:GetService('RunService').RenderStepped:wait()
			clone.Size = clone.Size + Vector3.new(.2,.2,0)
		end
	end
end)

mouse.KeyUp:connect(function(key)
	if key == 't' then
		chr.Humanoid.WalkSpeed = 16
		for i = 1,25 do
			game:GetService('RunService').RenderStepped:wait()
			clone.Size = clone.Size - Vector3.new(.2,.2,0)
		end
		clone:Destroy()
	end
end)

line 3, change it to

chr = plr.Character

and on line 1 add

repeat wait() until game.Players.LocalPlayer

that or you can just add a wait(2) and it will work perfectly fine!
