@Γιάννης-and-Ρένα0 if you do a search on this community you will find multiple hosts complaining about the same thing.
If you have good ratings, what is likely to have happened is a recent guest raised a 'safety' concern about your listing. This is sometimes if you have CCTV, or you have a problem guests who makes up a revenge complaint if you have caught them out breaking your house rules.
If this is what happened Airbnb will not tell you what the issue is or give you an opportunity to put across your side of the story. Then after 5-20 days hopefully you will get your listing back.
This is an appalling policy on Airbnb's part and despite concerns raised they refuse to do anything about it.
