My laser projectile script doesn't work why? [BodyVelocity & Touched]

It deals damage until the player finally dies. Then the projectile just freezes in the air. Heres the script maybe you can test it and find out it's problem :(

repeat wait() until game.Players.LocalPlayer.Character

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local camera = game.Workspace.CurrentCamera
local speed = 100

enabled = false

function shootBeam(key)
	if key.KeyCode == Enum.KeyCode.F and enabled == false then
		enabled = true
		print("pew pew!")
		
local laser = Instance.new("Part", workspace)
		laser.Name = "laserBeam"
		laser.Anchored = false
		laser.CanCollide = false
		laser.Transparency = 0
		laser.FormFactor = Enum.FormFactor.Custom
		laser.Material = Enum.Material.Neon
		laser.BrickColor = BrickColor.new("Lime green")
		laser.Size = Vector3.new(0.5, 0.5, 2)
		laser.CFrame = player.Character.Torso.CFrame *CFrame.new(0, 1.5, -2.5)
		
		local bodyvelocity = Instance.new("BodyVelocity", laser)
		bodyvelocity.velocity = player.Character.Torso.CFrame.lookVector * speed
		
		local debounce = false
		
		laser.Touched:connect(function(hit)
			if hit.Parent:FindFirstChild("Humanoid") ~= nil and debounce == false then
				debounce = true
				hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health - 15
				wait(2)
				debounce = false
			end
		end)
		
		game:GetService("Debris"):AddItem(laser, 2)
		wait(1)
		enabled = false
	end
end

game:GetService("UserInputService").InputBegan:connect(shootBeam)
