Какая ошибка в скрипте в роблокс студио

Question

Мне нужно найти ошибку, сначало скрипт работал а потом перестал  резко работать
Скрипт на анимацию я ставил
local Player = game.Players.LocalPlayer
	local Character = workspace:WaitForChild(
Player.Name
)
		local Humanoid = Character:WaitForChild('Humanoid')
local RunAnimation = 
Instance.new
('Animation')
RunAnimation.AnimationId = 'rbxassetid://Run'
RAnimation = Humanoid:LoadAnimation(RunAnimation)
Running = false
function Handler(BindName, InputState)
	if InputState == Enum.UserInputState.Begin and BindName == 'RunBind' then
		Running = true
		Humanoid.WalkSpeed = 50
	elseif InputState == Enum.UserInputState.End and BindName == 'RunBind' then
		Running = false
		if RAnimation.IsPlaying then
			RAnimation:Stop()
		end
		Humanoid.WalkSpeed = 16
	end
end
Humanoid.Running:connect(function(Speed)
	if Speed >= 10 and Running and not RAnimation.IsPlaying then
		RAnimation:Play()
		Humanoid.WalkSpeed = 50
	elseif Speed >= 10 and not Running and RAnimation.IsPlaying then
		RAnimation:Stop()
		Humanoid.WalkSpeed = 16
	elseif Speed < 10 and RAnimation.IsPlaying then
		RAnimation:Stop()
		Humanoid.WalkSpeed = 16
	end
end)
Humanoid.Changed:connect(function()
	if Humanoid.Jump and RAnimation.IsPlaying then
		RAnimation:Stop()
	end
end)
game:GetService('ContextActionService'):BindAction('RunBind', Handler, true, Enum.KeyCode.LeftShift)
