I also have an issue where the same Alert is displayed.
The error below occurs on the device I have secured.
Default 15:42:44.399960+0900 online-auth-agent Error Domain=com.apple.MobileActivation.ErrorDomain Code=-16 "UCRT healing required but not supported (user signed into non-HSA2 iCloud account)." UserInfo={NSLocalizedDescription=UCRT healing required but not supported (user signed into non-HSA2 iCloud account).}
