Bug ITMS-90338: Non-public API usage

Today I tried to upload a new version of my app to AppStore and received this error:

ITMS-90338: Non-public API usage - The app references non-public selectors in Frameworks/UnityFramework.framework/UnityFramework: callWithArguments:, estimatedProgress, frameInfo, initWithFrame:configuration:, initWithVirtualMachine:, isMainFrame, isNumber, isObject, loadPlugin, setProcessPool:, sourceFrame, targetFrame, toDouble, userContentController, virtualMachine. 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/

There weren't any third party SDK or Unity updates since the last version.
I'm using Unity 2020.3.33f1 with MacOS Big Sur 11.6 and XCode 13.2.1.

It also seems to be happening with react-native: https://github.com/facebook/react-native/issues/33789

 

Seems like it was an Apple issue:

It's working now
