Strange Delay with My Zombie Script

I am having trouble with my zombie script again, when the zombie spawns in it plays an animation and when it finishes goes to normal activity. The problem occurs before it continues with it’s normal patrolling, for some reason there is a large delay, I don’t know what the problem is. Here is the entire AI script:

local pathfindingService = game:GetService("PathfindingService")
local RunService = game:GetService("RunService")
local TweenService = game:GetService("TweenService")
local DebrisService = game:GetService("Debris")

local entity = script.Parent
local humanoid = entity.Humanoid
local defaultWalkSpeed = humanoid.WalkSpeed
local sightDistance = 60
local attackRange = 6
local attackDelay = 1.5
local damage = 15
local attackAnim = humanoid:LoadAnimation(script.Attack)
local deathAnim = humanoid:LoadAnimation(script.Death)
local spawnAnim = humanoid:LoadAnimation(script.Spawn)
local canAttack = true
local canDie = true

entity.HumanoidRootPart:SetNetworkOwner(nil)

local function canSeeTarget(target)
	local origin = entity.HumanoidRootPart.Position
	local direction = (target.HumanoidRootPart.Position - entity.HumanoidRootPart.Position).unit * sightDistance
	local ray = Ray.new(origin, direction)
	
	
	local hit, pos = workspace:FindPartOnRay(ray, workspace.Zombies)
	
	if hit then
		if hit:IsDescendantOf(target) then
			return true
		else
			return false
		end
	end
end

local function findTarget()
	local players = game.Players:GetPlayers()
	local maxDistance = sightDistance
	local nearestTarget
	
	for index, player in pairs(players) do
		if player.Character then
			local target = player.Character
			local distance = (entity.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude
			
			if distance <= maxDistance and canSeeTarget(target) and target.Humanoid.Health > 0 then
				nearestTarget = target
				maxDistance = distance
			end
		end
	end
	
	return nearestTarget
end

local function getPath(destination)
	local pathParams = {
		["AgentHeight"] = 5, 
		["AgentRadius"] = 2.6,
		["AgentCanJump"] = false
	}
	local path = pathfindingService:CreatePath(pathParams)

path:ComputeAsync(entity.HumanoidRootPart.Position, destination.Position)
	
	return path
end

local function generateSound(folder)
	local randomNumber = Random.new()
	local possibleSounds = folder:GetChildren()
	local randomSound = possibleSounds[randomNumber:NextInteger(1, #possibleSounds)]
	local selectedSound = randomSound:Clone()
	selectedSound.Parent = entity.HumanoidRootPart
	
	return selectedSound
end

local function attack(target)
	local distance = (entity.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude
	
	if distance <= attackRange and canAttack then
		canAttack = false
		attackAnim:Play()	
		attackAnim:GetMarkerReachedSignal("Attack"):Wait()
		if (entity.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude <= attackRange then
			target.Humanoid.Health -= damage
		end
		
		attackAnim.Ended:Wait()
		task.wait(attackDelay)
		canAttack = true
	end
end

local function patrol()
	local target = findTarget()
	local attackCo = coroutine.create(attack)
	if target then
		coroutine.resume(attackCo, target)
		humanoid:MoveTo(target.HumanoidRootPart.Position)
	end
end

local function death()
	canDie = false
	entity.HumanoidRootPart.Anchored = true
	entity.HumanoidRootPart.Death:Play()
	
	deathAnim:Play()
	deathAnim:GetMarkerReachedSignal("Death"):Wait()
	entity:Destroy()
end

RunService.Heartbeat:Connect(function()
	if humanoid.Health <= 0 and canDie then
		death()
	else
		patrol()
		wait(0.01)
	end
end)

local function entitySpawned(property)
	if property == "Parent" then
		local forceField = Instance.new("ForceField")
		forceField.Visible = false
		forceField.Parent = entity

		entity.HumanoidRootPart.Anchored = true
		canAttack = false

		spawnAnim:Play()
		spawnAnim.Ended:Wait()

		entity.HumanoidRootPart.Anchored = false
		canAttack = true
		forceField:Destroy()
	end
end

entity.Changed:Connect(entitySpawned)
