If them interrupting becomes a problem, I would tell them: “It will not work. Even if you ‘fix’ something, it will often still not work. Your _task_ is to find the errors yourself. Try as many things for the next five (ten) minutes. Then I will go around and help you”.
If that does not work, I tell them: I will go around in _this_ order and help you, until then please stay as quiet as possible so that the others can concentrate.
But both have only limited effect, depending on age and other factors. I cannot completely avoid this behavior (mostly with male students)
