Why isnt my non-cancollide player script working?

This is in a local script and the game is filtering enabled, the script is inside startergui. It doesn't work at all.

local localPlayer = game.Players.LocalPlayer

game["Run Service"].RenderStepped:connect(function()
	for _, player in pairs(game.Players:GetPlayers()) do
		local character = player.Character
		if character and localPlayer.Character ~= character and character:FindFirstChild('Torso') then
			character.Torso.CanCollide = false
			character.Head.CanCollide = false
		end
	end
end)
