How do I make animations work when I press Q in ROBLOX player?

Here is the download to the game: https://mega.nz/fm/Ua4EGBDZ When you press Q, you are meant to punch. It works in studio, but not in roblox player. It's an FE enabled game with r15 characters. It only gives one error in roblox player; "Infinite yield possible on ServerScriptService("Punch")", something like that, but you can see yourself.

Well to start you need a local script. in this local script you will be able to press Q to punch, it will play the animation, and fire tuple arguments to the server to see if it should punch

The local script should be in StarterCharacterScripts, and should look something like this:

local UIS = game:GetService('UserInputService')
local RS = game:GetService('ReplicatedStorage')

local PunchEvent = RS:WaitForChild('PunchEvent')

local Punching = false
local Damaging = false

local Char = script.Parent
local Humanoid = Char.Humanoid
local RightHand = Char:WaitForChild('RightHand')

local PunchAnimation = Instance.new('Animation') -- define the animation instance, or make an animation instance

PunchAnimation.AnimationId = 'rbxassetid://67584958' -- if you have a new instance animation, make sure to set the right id

local Damage = 20 -- put damage here

UIS.InputBegan:connect(function(input)
	if input.KeyCode = Enum.KeyCode.Q then
		if not Punching then
			Punching = true
			Damaging = true
			local PunchTrack = Humanoid:LoadAnimation(PunchAnimation)
			PunchTrack:Play()
			PunchTrack.Stopped:wait()
			Punching = false
			Damaging = false
		end
	end
end)

RightHand.Touched:connect(function(hit)
	if hit.Parent:FindFirstChildOfClass('Humanoid') and Punching and Damaging then
		Damaging = false
		PunchEvent:FireServer(hit.Parent:FindFirstChildOfClass('Humanoid'), Damage)
	end
end)

now there should be an event in ReplicatedStorage and a server script in ServerScriptService. in this script should be something like this:

local PunchEvent = game:GetService('ReplicatedStorage'):WaitForChild('PunchEvent')

PunchEvent.OnServerEvent:connect(function(client, HumanoidToDamage, Damage)
	HumanoidToDamage:TakeDamage(Damage)
end)

this should allow for the animation to play, and the damage to be done
