:AdjustSpeed not working

[nocm1887cc (Name)]

i make a script that when player hold the button the animation will freeze until they release the button, it work fine before i optimize something

freeze animation

if CMoves.Animation ~= nil then
				CMoves.Animation:Play()
			end

			if CMoves.Set == true then
				if CMoves.Animation ~= nil then
					CMoves.Animation:GetMarkerReachedSignal("Hold"):Once(function()
						if KeyCode[Keybind] == true then
							print(3)
							CMoves.Animation:AdjustSpeed(0)
						end
					end)
				end

it does print 3

animation load

function CharacterLoad(VCharacter)
	Character = VCharacter
	
	Human = Character:WaitForChild("Humanoid")
	local Animator = Human:WaitForChild("Animator")
	
	Animation = Animator:LoadAnimation(script.Hold)
	ReleaseAnimation = {
		[1] = Animator:LoadAnimation(script.One),
		[2] = Animator:LoadAnimation(script.Two),
		[3] = Animator:LoadAnimation(script.One)
	}
end
