An iOS app that I had set up a pre-order for was delivered on its own the day before the release date. Why? When I look at the settings screen of the app in App store connect, it still says that the app has not been distributed yet. It says "1.2 Pre-orders are ready for delivery" and the "Release App Now" button is displayed. In this state, the app has already been released. How can this happen?

When I try to upload to apple store connect from XCODE, I get the following error. "the app contains one or more corrupted binaries. rebuild the app and resubmit. with error code state_error.validation_error.10 for id *****" This error started appearing suddenly today. I have not made any major changes since yesterday. It had never appeared before. I get the same error when I try to re-upload other app builds that I was able to upload before. "state_error.validation_error.10" error code does not show up at all when I search google. Also When I upload an exported build via Transporter, I get an email with the error "ITMS-90338: Non-public API usage". I have tried restarting the MAC, clean build of XCODE, etc., but to no avail. Can someone please help me? (My environment is XCODE13 and Unity2020.)
