REO sale stopped by bankruptcy

Hey. We had a property under contract and we were 2 days from closing when we found out Fannie Mae didn’t have title to the house because the owner filed chapter 7 bankruptcy within 10 days after the foreclosure sale (NC law). This was going to be my permanent residence and not a flip. The bankruptcy is a Chapter 7, no assets and the owner has moved out. What would be my best course of action to still make this deal happen?

Thanks!
