User input service not working suddenly?

Script worked a few days ago. Suddenly doesn't work.

real = false
script.Parent.Equipped:Connect(function()
 real = true
	end)
	script.Parent.Unequipped:Connect(function()
	real = false
	end)
game:GetService("Players").PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
local LocalPlayer = game:GetService("Players").LocalPlayer
local Controls = require(LocalPlayer.PlayerScripts.PlayerModule):GetControls()
local UIS = game:GetService("UserInputService")
local character = game.Workspace:WaitForChild(game.Players.LocalPlayer.Name)
local boom = character:WaitForChild("Humanoid") :LoadAnimation(script:WaitForChild("boom"))
		

UIS.InputBegan:Connect(function(key,chat)
	if chat then return end
	if real == false then return end
	if key.KeyCode == Enum.KeyCode.E then
				boom:play()
		end
		end)
	end)
	end)

Did the new studio update break UIS?
