Inventory slot selection suddenly stopped working

[oomer1 (Pufferfish)]

I made a inventory slot selection system where it adds a click function on each inventory slot. It was working perfectly fine a few hours ago, but now the click function isnt firing at all.

Client inventory script:

local inventory = {}

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

local ts = game:GetService("TweenService")
local StarterGui = game:GetService("StarterGui")

local UserInputService = game:GetService("UserInputService")

local remotes = ReplicatedStorage:WaitForChild("Remotes")
local changeSlotRemote = remotes:WaitForChild("UpdateInventorySlots")
local getInv = remotes:WaitForChild("GetPlayerInventory")

local popup = require(ReplicatedStorage:WaitForChild("ClientModules"):WaitForChild("PopupPrompts"))
local launch = require(ReplicatedStorage:WaitForChild("ClientModules"):WaitForChild("LaunchClient"))
local menu = require(ReplicatedStorage:WaitForChild("ClientModules"):WaitForChild("MenuClient"))

inventory.inv = nil

inventory.Ready = false

local selectedSlot = nil
local defaultSelectedBlock = ReplicatedStorage:WaitForChild("Blocks"):WaitForChild("Wood_Planks")
local defaultBlockId = defaultSelectedBlock:GetAttribute("BLOCKID")
inventory.selectedBlock = defaultSelectedBlock

local slotCache = {}
local _, _, defaultGrayV = Color3.fromRGB(71, 71, 71):ToHSV()

local clearDebounce = false

local function findBlockName(blockId)
	local blockFolder = game.ReplicatedStorage.Blocks
	for _, block in pairs(blockFolder:GetChildren()) do
		local id = block:GetAttribute("BLOCKID")
		if id then
			if id == blockId then
				return {DisplayName = block:GetAttribute("DisplayBlockName"), Block = block}
			end
		end
	end
end

local function selectSlot(slot, highlightColor, holdingFrame, block)
	print(slot)
	if not slot or not highlightColor or not holdingFrame then return end

	inventory.selectedSlot = slot

	for _, v in pairs(holdingFrame:GetChildren()) do
		if v:IsA("Frame") and v:FindFirstChild("Stroke") then

remotes:WaitForChild("UpdateInventorySlots").OnClientEvent:Connect(function(blockId, amount)
	updateSlot(blockId, amount)
end)

local updateCooldown = false

return inventory

The first slot added works but not the second.

I added checks if the slot and button exists and it does. But when I click on the button it doesnt print ‘clicked.’

I also tried disabling this function and nothing changed:

local function checkIfLaunched(team)
			--print(team)
			--if not team then return end
			--local plots = workspace:WaitForChild("Plots")
			--local teamPlot = plots:FindFirstChild(team.Name)
			--if not teamPlot then return end
			--local launchedVal = teamPlot:FindFirstChild("Launched")
			--if not launchedVal then return end

			return false
		end

The only changes to this script today was add these:

	if not launched then
			print("3")
			launch.Show()
			menu.Show()
		else
			print("4")
			launch.Hide()
			menu.Hide()
			menu.CloseFrame()
		end

else
		playerList.Enabled = true
		launch.Hide()
		menu.Hide()
		menu.CloseFrame()
	end

I tried commenting those out but it still didnt do anything.
