This happens with a clean project also, it works fine when I manually embed files in the "Targets → Unity-Phone → General → Frameworks, Libraries, and Embedded Content", but I'm afraid that in that case there may be other issues. (not passing validation for example). Doe's apple embed Frameworks to correct target? Because frameworks were embedded to "UnityFramework" and the game still crashes, the game does not crash when they are embedded to "Unity-iPhone" target manually. Can anyone do a clean build with sample project to confirm? I'm using Unity 2021.3
