The official rules require a world to be newly published on Horizon. Please note that all the other entry requirements still apply, including that the world is original to the entrant. FAQs have been updated here: https://mhcp-mobile-genre-competition.devpost.com/details/faq
Can I take the assets I used in the world I published and incorporate them into a new unpublished world that has the same name and still be eligible?
From the official rules.
Be newly published by the Entrant, publicly viewable by any user of Meta Horizon Worlds during the duration of the competition and not have been previously entered into any other challenge, sweepstakes, promotion, or competition. However, an Entry may use assets or code from Entrant’s existing Meta Horizon worlds, or from tutorials or examples provided to Entrant by Sponsor.
