Need help playing animations

[xiiitixxtxxtxxxxiiix (Lua)]

i have made a script where the player should play an animation when they press left control

it does print but wont play the animation at all

local ContextActionService = game:GetService("ContextActionService")

local Player = game.Players.LocalPlayer
local character = Player.Character or Player.CharacterAdded:Wait()

local humanoid = character.Humanoid
local animator = humanoid:FindFirstChild("Animator")
print(animator.Name)
local CrouchingAnimation = script.Crouch

local isCrouching = false

local function CrouchFunc(actionName, inputState, _inputObject)
	local CrouchTrack = animator:LoadAnimation(CrouchingAnimation)
	if actionName == "Crouching" and inputState == Enum.UserInputState.Begin then
		if not isCrouching then
			print("Play CrouchingAnimation")
			isCrouching = true
			humanoid.JumpHeight = 0
			CrouchTrack:Play()
		else
			print("Stop Crouching")
			isCrouching = false
			humanoid.JumpHeight = 7.2
			CrouchTrack:Stop()
		end
	end
end

ContextActionService:BindAction("Crouching", CrouchFunc, true, Enum.KeyCode.LeftControl, Enum.KeyCode.ButtonL1)

yes i used the right animation ids
