Based on another thread, wrapping the modelContext.insert and modelContext.save in DispatchQueue.main.async fixed the issue.

@ShaySal219 Did you get this figured out? Got a similar message this morning.

@Help_Developer Did you figure out why account was flagged for compliance screening? Did it get resolved?

Maybe if you go to developer.apple.com/account ? There's a section there for "Agreements"
