i cant seem to prevent game script timeout (?)

im making a tutorial and want to go to the next information only when the previous info was used, in this case til the user clicks a cube, but every time it gets to that point and i click the cube, studio stops responding for a little bit and it says "game script timeout" and just doesnt work. it was fine and worked well til i added the "repeat" part

local text = "To start, Left Click the cube."
game.Workspace.Map.TutorialRestriction.Invis1.CanCollide = false
script.Parent.Tutorial.Click.Playing = true
for i = 1, #text do
    script.Parent.Tutorial.Gui.TextLabel.Text = string.sub(text, 1, i)
    wait(0.0625)
end
if text ==  "To start, Left Click the cube." then 
	script.Parent.Tutorial.Click.Playing = false
	repeat
	if game.Workspace.Interactables.Cube.Anchored == false then
		script.Parent.Tutorial6.Disabled = true
	end
	until script.Parent.Tutorial6.Disabled == false
end
