Anyone know who accepts UHC HMO Silver D+?

I’m honestly just whipped. I’ve called 30+ places that my UHC app & website said I’m in network for and they’ve all said no because it’s a marketplace plan. specifically, anyone know of any OGBYNs that accept marketplace plans? i don’t know what else to do as i’ve called UHC member services and was put on hold for over an hour each time because they also couldn’t find anyone.
