Repeat until keep's crashing studio?

I am trying to make this work until the BoolValue's value is changed to false, but it keep's crashing my studio even with a wait. Can someone tell me how to fix it?

Here is the code.

val = script.Parent.on -- BoolVaue
g1 = script.Parent.G1 -- Model

val.Changed:connect(function()
	if val.Value == true then
		repeat until val.Value == false
		wait(0.02)
		for _,v in pairs(g1:GetChildren()) do
			if v.Name == "Light" then
				v.Point.Enabled = true
				v.Lighto.Enabled = true
				wait(0.02)
				v.Point.Enabled = false
				v.Lighto.Enabled = false
				wait(0.02)
			end
		end
	end
end)
