Facebook Marketplace is not working. Saying “Marketplace isn’t Available to You”

So just recently my marketing out of nowhere just disappeared from my app. When I try to search it this is what comes up. I buy and sell a lot so marketplace is kind of a necessity for me. Any ideas on how to fix this? Thanks
