it seems your cover image is AI generated, even if your assets are your own or with license, you shouldn't publish a AI cover, there is still time, try making a new game page submission, head to https://www.photopea.com/ and build up a cover image there, or any other FOS tool
not like that... I told you "try making a new game page submission", your current one was disqualified so it doesn't work if you just remove the rule breaking problem :(
anyway, itch.io overall does not approve AI, there might be some jam here and there that does but they are never featured, use AI only for mockups, but do the work yourself, this is what they intend for the jams, being a indie dev
