uis.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.E and debounce.Value and debounce2 then
		debounce2 = false
		if humanoid.Health > 0 and char.Parent ~= nil then
			animationTrack:Play()
			wait(0.2)
			game.ReplicatedStorage.events.swordevent:FireServer('equip')
			wait(0.6)
			debounce2 = true
		end
	end
end)

Code runs fine the first time but when player resets the error: Cannot load the AnimationClipProvider Service happends. It is a local script under a tool in starter pack.
