Why do the animations not play, but the sound effects do? And how can I make them play?

I've changed my code but it still doesn't work?

script.Parent.OnServerEvent:connect(function(Player, Action, V1)
	local c = Player.Character or Player.CharacterAdded:Wait()
	if Action == "Release" then 
		ButtonDown = false
	end
	if Enabled == false  then return end
	if Action == "Combat" then 
		Enabled = false
		local Humanoid = c:WaitForChild("Humanoid")
		local Animator = Humanoid:WaitForChild("Animator")
		if Combo == 1 then
				Combo = 2
				local Track = Instance.new("Animation")
				Track.AnimationId = "rbxassetid://11285688290"
				local Anim = Animator:LoadAnimation(Track)
				Anim:Play()
				wait(0.5)

Enabled = true
ButtonDown = false
Combo = 1
	
script.Parent.OnServerEvent:connect(function(Player, Action, V1)
	local c = Player.Character or Player.CharacterAdded:Wait()
	if Action == "Release" then 
		ButtonDown = false
	end
	if Enabled == false  then return end
	if Action == "Combat" then 
		Enabled = false
		if Combo == 1 then
				Combo = 2
				local Track = Instance.new("Animation")
				Track.AnimationId = "rbxassetid://11285688290"
				local Anim = c.Humanoid:LoadAnimation(Track)
				Anim:Play()
				wait(0.5)
			elseif Combo == 2 then
				Combo = 3
				local Track = Instance.new("Animation")
				Track.AnimationId = "rbxassetid://11285688290"
				local Anim = c.Humanoid:LoadAnimation(Track)
				Anim:Play()
				wait(0.5)
			elseif Combo == 3 then
				Combo = 1
				local Track = Instance.new("Animation")
				Track.AnimationId = "rbxassetid://11285688290"
				local Anim = c.Humanoid:LoadAnimation(Track)
				Anim:Play()
				wait(0.5)
			end
			end
			wait(0.09)
			local Region = Region3.new(V1-Vector3.new(3,3,3),V1+Vector3.new(3,3,3))
			local RTable = workspace:FindPartsInRegion3(Region, nil, 20)
			for i,v in pairs(RTable) do
				if v.Parent:findFirstChild("Humanoid") and v.Parent:findFirstChild("Deb") == nil and v.Parent ~= c then
					local Deb = Instance.new("BoolValue", v.Parent)
					Deb.Name = "Deb"
					game.Debris:AddItem(Deb,0,2)
					v.Parent.Humanoid:TakeDamage(5)
					local S = Instance.new("Sound", v)
					S.SoundId = "rbxassetid://11285764868"
					S.PlaybackSpeed = math.random(80,120)/100
					S:Play()
				end
		Enabled = true
	end 
end)

Humanoid:LoadAnimation does not work anymore. Use a "Animator" Instead

What prints in the console?

Maybe try giving a parent to the animation?

Edit: Ok so are you sure the "Play()" line is being ran through? you can do "print("Playing") right above the "Play()" line to see if it is, if "Playing" doesn't print that means the Action isn't working properly.

Otherwise I'm not sure what could be the issue, as in my case, I make the animations before, and I place them in a folder inside a tool, so i can use them, here is an example of my code for a knife weapon:

function ActionManager()
	if playingIdle == true then
		if Attacking == false then
			Attacking = true

			--- Combo String
			if ComboNum == 0 then
				ComboNum = 1
				Slash1()
			elseif ComboNum == 1 then
				ComboNum = 0
				Slash2()
			end


			wait(0.2)
			Attacking = false
		end

	end
end

knife.Activated:Connect(ActionManager)

local Anim_Slash1 = knife.Handle.Animations.Slash1
local Slash1Anim = holderChar.Humanoid:LoadAnimation(Anim_Slash1)

function Slash1()
	Slash1Anim:Play()

	wait(0.16)

	local SlashSounds = SoundsFolder.SlashSounds:GetChildren()
	local randomSlash = SlashSounds[math.random(1, #SlashSounds)]
	randomSlash:Play()
end

Maybe you can try making the animations beforehand like i did with my code? If that doesn't work I have no idea what could be the issue

Hello! I am currently working on a solution (which I'm sure I almost have figured out) and will be updated ASAP.
