Your app includes a version of an SDK from Yandex that violates the App Store Review Guidelines. The version of the Yandex SDK you are using in your app attempts to hide the use of private APIs.
Next Steps
To resolve this issue, please either remove the Yandex SDK entirely from your app, or revise your app to utilize version 2.9.8 or 3.1.2 of the Yandex SDK. Once you have made one of those changes, resubmit your binary for review.
