Something has changed with Apple (unless the AppGameKit apps use a server to package to an IPA) which is automatically rejecting uploads to App Store Connect. They get through Transporter without any issues but after it successfully delivered an automatic email is sent saying they found issues with the app and then it fails to appear on App Store Connect
This is the error they give in the email (see below)
I have tried updating Xcode, redownloading Studio, and restarting the Mac. Same error every time. I last succesfully uploaded last week so something has changed within the last few days.

Dear Developer,
We identified one or more issues with a recent delivery for your app, "ChastiKey" 2.6.0 (231). Please correct the following issues, then upload again.
ITMS-90338: Non-public API usage - The app references non-public symbols in ChastiKey: _kCGColorSpaceITUR_2020_HLG, _kCGColorSpaceITUR_2020_PQ_EOTF. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed. For further information, visit the Technical Support Information at http://developer.apple.com/support/technical/
Best regards,
The App Store Team
