I am working on a backrooms game, when i made the flashlight, the animation dont seem to animate correctly on the first time, its kinda wierd and getting annoying, i don’t know why thats happening

Flashlight Local Script:

local UserInputService = game:GetService("UserInputService")
local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local LocalPlayer = Players.LocalPlayer
local Character = LocalPlayer.Character

local Assets = ReplicatedStorage.Assets
local Events = ReplicatedStorage.Events

LocalPlayer.CharacterAdded:Connect(function(NewCharacter)
	Character = NewCharacter
end)

local Keys = {
	Enum.KeyCode.F,
	Enum.KeyCode.ButtonX
}

local Debounce = true

UserInputService.InputBegan:Connect(function(Key)
	for i,v in pairs(Keys) do
		if Key.KeyCode == v and Debounce == true and LocalPlayer.Character.CanFlashlight.Value == true then
			Debounce = false
			
			Events.Flashlight:FireServer(LocalPlayer)
			wait(1)
			Debounce = true
		end
	end
end)

Flashlight Server Script:

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Assets = ReplicatedStorage.Assets
local Events = ReplicatedStorage.Events

Animation = nil

Events.Flashlight.OnServerEvent:Connect(function(Player)
	if Player.Character:FindFirstChild("FlashlightPart") then
		local NewSound = Player.Character.FlashlightPart.Value.Off:Clone()
		NewSound.Parent = Player.Character.Head
		NewSound:Play()
		Player.Character.FlashlightPart.Value:Destroy()
		Player.Character.FlashlightPart:Destroy()
		Animation:Stop()
		Animation = nil
		wait(1)
	else
		local FlashlightPart = Player.Character:FindFirstChild("Right Arm")

		local Attachment = Instance.new("Attachment")
		Attachment.Parent = FlashlightPart
		Attachment.Position = Vector3.new(0,-FlashlightPart.Size.Y/2,0)
		Attachment.Orientation = Vector3.new(90,0,0)

		local NewFlashlight = Assets.Flashlight:Clone()
		NewFlashlight.Parent = workspace
		NewFlashlight.CFrame = Attachment.WorldCFrame

		local ObjectValue = Instance.new("ObjectValue")
		ObjectValue.Parent = Player.Character
		ObjectValue.Name = "FlashlightPart"
		ObjectValue.Value = NewFlashlight

		local NewSound = NewFlashlight.Click:Clone()
		NewSound.Parent = Player.Character.Head
		NewSound:Play()

		local Weld = Instance.new("WeldConstraint")
		Weld.Parent = FlashlightPart
		Weld.Part0 = FlashlightPart
		Weld.Part1 = NewFlashlight

		local NewAnimation = Player.Character.Humanoid:LoadAnimation(script.FlashlightAnimation)
		NewAnimation.Priority = Enum.AnimationPriority.Action4
		NewAnimation:Play()
		wait(NewAnimation.Length - 0.1)
		NewAnimation:AdjustSpeed(0)
		Animation = NewAnimation
	end
end)
