Recently there's been yet another case of a certain unpleasant situation I myself experienced to an extent shortly after joining WBSE.
Essentially, it all begins when an inadequate question is asked and closed due to its problems, but the closure occurs only after an answer has already been posted.
The question is, as of now, still inadequate and thus to be reopened it needs to be edited to fix the problems it has. The big issue here comes from the fact that, since it already has answers, which were written with the still inadequate question in mind, it can't make any edits that would invalidate the answer. This means that, for as long as the answer remains, the question essentially cannot be fixed since any edits that would solve the original problems will be rolled back as to not to invalidate the already existing answers.
Furthermore, the presence of the answer also means that the question can't be deleted by the original poster before they can ask a new one, and even if they could, unless they managed to make this new question look drastically different, it could and likely would be framed as a duplicate (if the question is still around) or even as an attempt to bypass the closure if they did manage to delete the original.
Summing up, my question is: in the situation that a user has asked a question that does not originally conform to the rules, but has already received answers that prevent them from making the necessary adjustments, how should said user solve the problem? Should they flag the question and hope it's deleted? Perhaps ask any users who have answered the question to delete their posts in order to allow for the fixes to be made? Should they simply give up on asking about the topic they wanted help with altogether because their question fell victim to this cycle?
The main reason I'm asking this is because the most recent case I've seen hasn't been the only recent case I noticed, with a second, slightly older case in which the situation was thankfully solved, but only because the user who had answered the originally inadequate question was kind enough to adequate their answer to conform to the clarifying edits made by the OP (edits which, as a matter of fact, had been rolled back for the very reason that clarifying the problem invalidated the original answer).
I'm not disputing the policy, as I understand both the effort some users put into their answers and the importance of preventing scenarios in which one can essentially ask a new question by editing an old post at any moment (even if I do believe exceptions to this rule should be available, especially for certain specific loophole problems such as this one). I'm simply seeking a potential best course of action for people (particularly new users unaccustomed with the SE's rules) who happen to fall in such a situation.
