Infinity yield possible how to solve this?

Hello guys i have a script for tool removing but i get this error on output

local player = game:GetService("Players")
local backpack = player:WaitForChild("Backpack")
local removableLaunchers = {"SledgeHammer"}

local function purgeLaunchers(container)
	for _, launcher in pairs(removableLaunchers) do
		local tool = container:FindFirstChild(launcher)
		if tool and tool:IsA("Tool") then
			tool:Destroy()
		end
	end
end

purgeLaunchers(backpack)
purgeLaunchers(player)

local backpack = player:WaitForChild("Backpack") for second line the outputs says infinity yield possible how to solve this?

So we meet again TheMostDelikanliMan!

Your issue here is simple!

local player = game:GetService("Players")

You defined "player" as the games PlayerService itself!

Backpack is a child of the player object! Therefore, you need to do what is listed below.

local player = game:GetService('Players').LocalPlayer

For future reference, you get the Infinite Yield error if the child is not present. You need to make sure that the object/item you're putting inside of the :WaitForChild('') is inside of the parent.
