My “fuck buddy” ghosted me six months ago. I will see her at a mutual friends’ get together this weekend? Should I ask her what happened?

I had a fuck buddy arrangement going on for about a month. Then she randomly ghosted and blocked me on everything. I’ll be seeing her at a friend’s housewarming party this weekend.

Should I confront her and ask her what happened?
