Need some serious advice!

So here's an update on my book, so i finished and published it on KDP, an i have done a big f*up, so first I used AI to create book cover and so the title was Act 1: The Iron Assembly - Beyond the throne, but one the cover, iron was written two times, and for some reason i didn't noticed it. like till book was live on amazon and after writing it, i asked someone to proof read it as i was tired, but they didn't read and just said it's good and I had uploaded the unedited version. I unpublished the book, so now i fixed those problems but had to change the title but i just learnt that I cannot change title after publishing it in kdp, so now i have some options, either rewrite whole thing, change style, character names, places to avoid legal consequences of any kind, as they don't allow you to publish same thing with different name and cover, 2nd i can just publish it with new cover with different title on cover and different title on their site but with the edited version, or i let my work remain unpublished forever and publish the chapter here free of cost chapter by chapter. do give me suggestions if you have.
