LocalScript that should enable a gui doesnt work, what to do?

Hello, ive made a localscript that gets enabled by a normal script that should enable a value and a gui, but it doesnt seem to work at all. The localscript gets enabled and all but it just doesnt do anything. The LocalScript is also inside the StarterPlayerScripts folder, ive tried multiple before but it didnt work. Heres the code that I made.

The MaskGui is a Gui that is disabled in StarterGui. The MaskValue is just a BoolValue in ServerStorage, its not too important.

local MaskGui = game.Players.LocalPlayer.PlayerGui.Mask
local MaskValue = game.ServerStorage.WearsMask

	MaskGui.Enabled = true
	MaskValue.Value = true

Also heres the code that I used to enable the localscript, it is inside a ProximityPrompt. MaskScript is the LocalScript that should run the code above.

local ProximityPrompt = script.Parent

ProximityPrompt.Triggered:Connect(function(player)
	game.StarterPlayer.StarterPlayerScripts.MaskScript.Disabled = false
end)
