Troubleshooting a crash on Unity Scene Load

Question

After upgrading my project to the latest Unity version, the Android build crashes when changing scenes.

This only happens on the built Android app, not in the editor or when built for desktop.

Here are the crash logs from adb logcat:

I have reverted the scene changing code to a basic

 public void LoadNext()
    {
        SceneManager.LoadScene(1);
    }

that is called by a button click, but it has made no difference.

Any help in deciphering the crash log or a direction to look into would be appreciated.

Answer 1

This seems to be a problem with Oculus utilities. If you have updated this there might be a problem with the android emulators using a disabled 32-bit display buffer (especially samsung devices)

Try enabling this and see if it works.

Answer 2

For anyone encountering a similar problem, I ended up exporting all the scenes and importing them into a previous version of Unity.

It did not technically solve the problem, but it did allow me to finish the project.
