why is my scrolling frame script keep on crashing?

when i press the button it just crashes

script.Parent.MouseButton1Click:Connect(function()
local name = game.Players.LocalPlayer.Name
local children = workspace.buythings:GetChildren()
local nr = 1
local onr = 0
for i = 1, #children do
	local child = children[i]
	local newz = script.Parent.Parent.Empty:Clone()
	newz.Text = child.Name
	newz.Position = UDim2.new(0,0,0,onr)
	script.Parent.Parent.CanvasSize = UDim2.new(0,0,0,onr)
	newz.Parent = script.Parent.Parent
	nr=nr+.5
	onr=onr+50
	wait(.1)
end
end)

Sometimes the Loop may run faster than your Computer can handle, in fact this is usually is the case. Simply slowing it down by .1 will not resolve your issue, the lowest you should go would be preferably .3 higher
