I updated to the latest version today and had the same error. I spent the whole day trying to figure out the problem, but couldn't.

If you are using Firebase.IOS.Analytics/Core Or MLKit(in your case), try downgrading all the packages to the previous version.

Have you ever resolved this or you just downgraded? I'm getting the exact same set of errors.
