That question was deleted by the “roomba” because of the last reason shown on the help page.
If it’s edited soon after closing, it doesn’t get deleted and can be re-opened easily.
Normally, the question being deleted with no answers, there’s no reason to rework it under the same ID but a new post is just fine. The auto-block algorithm is kept secret and may even be changed from time to time, but I do recall that deleting low-scoring posts doesn’t help (I got a notice to that affect when deleting a post).
Anyway, once you have a “good” version in the sandbox, one of us will help you get the post undeleted and, if necessary, paste the revised text into it.
Good luck, and thanks for sticking with it!
