"An error occurred" when using UserSettings?

Trying to index stuff but I keep getting the following error

18:02:40.197 - An error occurred 18:02:40.197 - Script 'Players.Player1.CirrusBin.mouseLockCheck', Line 9 - global check 18:02:40.198 - Script 'Players.Player1.CirrusBin.mouseLockCheck', Line 18 18:02:40.198 - stack end

Here is my code. (I'm using the Cirrus Framework designed by Team Rudimentality)

--[[
	Check if the player's MouseLock is on.
	
	
	
--]]

function check()
	if UserSettings().GameSettings.ControlMode.MouseLock == true then
		print("IT WORKS?!")
	else
		print("AWW...")
	end
end

while true do
	wait(1)
	check()
end
