AnimationTrack limit of 256 tracks for one Animator exceeded

Help and Feedback Scripting Support

I’m trying to create a script that plays a different variation of the “Run Animation” based on the direction the player is going in the first person

local hum = script.Parent:WaitForChild(“Humanoid”)
local uis = game:GetService(“UserInputService”)

local front = hum:LoadAnimation(script:WaitForChild(“Front”))
local back = hum:LoadAnimation(script:WaitForChild(“Back”))
local left = hum:LoadAnimation(script:WaitForChild(“Left”))
local right = hum:LoadAnimation(script:WaitForChild(“Right”))

uis.InputBegan:Connect(function(key)
if hum.FloorMaterial ~= Enum.Material.Air and script.Parent.Value.Crouch.Value == false then
if key.KeyCode == Enum.KeyCode.W then
front:Play()
script.Front.Value.Value = true
elseif key.KeyCode == Enum.KeyCode.S then
back:Play()
script.Back.Value.Value = true
elseif key.KeyCode == Enum.KeyCode.D then
right:Play()
script.Right.Value.Value = true
elseif key.KeyCode == Enum.KeyCode.A then
left:Play()
script.Left.Value.Value = true
end
else
front:Stop()
back:Stop()
right:Stop()
left:Stop()
end
end)

uis.InputEnded:Connect(function(key)
if key.KeyCode == Enum.KeyCode.W then
front:Stop()
script.Front.Value.Value = false
elseif key.KeyCode == Enum.KeyCode.S then
back:Stop()
script.Back.Value.Value = false
elseif key.KeyCode == Enum.KeyCode.D then
right:Stop()
script.Right.Value.Value = false
elseif key.KeyCode == Enum.KeyCode.A then
left:Stop()
script.Left.Value.Value = false
end
end)

hum:GetPropertyChangedSignal(“FloorMaterial”):Connect(function()
if hum.FloorMaterial == Enum.Material.Air then
front:Stop()
back:Stop()
right:Stop()
left:Stop()
repeat wait()
until hum.FloorMaterial ~= Enum.Material.Air
if script.Front.Value.Value == true then
front:Play()
elseif script.Back.Value.Value == true then
back:Play()
elseif script.Left.Value.Value == true then
left:Play()
elseif script.Right.Value.Value == true then
right:Play()
end
end
end)

The issue is that the animation suddenly stops along with all the other animations unrelated to the script. In the output, it spits out the error “AnimationTrack limit of 256 tracks for one Animator exceeded, new animations will not be played. (x36)”

Is this the whole script? Where is it located?

Are there any loops in it?

By looking at it I assume this is a local script in StarterPlayerCharacter. Is this correct?

Also please do format the code, it's very difficult to read. 
local hum = script.Parent:WaitForChild("Humanoid")
local animator = hum:WaitForChild("Animator")
local uis = game:GetService("UserInputService")

local front = animator:LoadAnimation(script:WaitForChild("Front"))
local back = animator:LoadAnimation(script:WaitForChild("Back"))
local left = animator:LoadAnimation(script:WaitForChild("Left"))
local right = animator:LoadAnimation(script:WaitForChild("Right"))

uis.InputBegan:Connect(function(key)
	if hum.FloorMaterial ~= Enum.Material.Air and script.Parent.Value.Crouch.Value == false then
		if key.KeyCode == Enum.KeyCode.W then
			front:Play()
			script.Front.Value.Value = true
		elseif key.KeyCode == Enum.KeyCode.S then
			back:Play()
			script.Back.Value.Value = true
		elseif key.KeyCode == Enum.KeyCode.D then
			right:Play()
			script.Right.Value.Value = true
		elseif key.KeyCode == Enum.KeyCode.A then
			left:Play()
			script.Left.Value.Value = true
		end
	else
		front:Stop()
		back:Stop()
		right:Stop()
		left:Stop()
	end
end)

uis.InputEnded:Connect(function(key)
	if key.KeyCode == Enum.KeyCode.W then
		front:Stop()
		script.Front.Value.Value = false
	elseif key.KeyCode == Enum.KeyCode.S then
		back:Stop()
		script.Back.Value.Value = false
	elseif key.KeyCode == Enum.KeyCode.D then
		right:Stop()
		script.Right.Value.Value = false
	elseif key.KeyCode == Enum.KeyCode.A then
		left:Stop()
		script.Left.Value.Value = false
	end
end)

hum:GetPropertyChangedSignal("FloorMaterial"):Connect(function()
	if hum.FloorMaterial == Enum.Material.Air then
		front:Stop()
		back:Stop()
		right:Stop()
		left:Stop()
		repeat wait()
		until hum.FloorMaterial ~= Enum.Material.Air
		if script.Front.Value.Value == true then
			front:Play()
		elseif script.Back.Value.Value == true then
			back:Play()
		elseif script.Left.Value.Value == true then
			left:Play()
		elseif script.Right.Value.Value == true then
			right:Play()
		end
	end
end)
