    We have exactly same problem!! We also tried to report it, however, couldn't create the sample project because it only occurs with our main project. We think it might happen only with real size project.

    To add, while we are changing scenes, we load B (loading) scene by executing "LoadScene" and B scene loads C scene by "LoadSceneAddictiveAsync." Then B scene destroys after C scene is completely loaded. The crash occurs after we call LoadSceneAddictiveAsync.

    The issue is on the way to a patch release. I would expect it earlier than 5.3.5 Keep an eye on the future patch release notes.

    I'm having a crash with a similar stack trace in the editor (in both 5.1.3 and 5.3.3) in my current project, when loading certain scenes in-game (both normal and async loading cause the issue). Is the fix just for iOS/Android for is this a more general issue?

    Our game is in the final stages for shipping and we are encountering the very same crash(log verified). Can you please push a patch at the earliest? We have tried even in 5.3.3 p2, the same issue exists.

    Thanks

    The fix will go in as soon as possible however it is still undergoing internal reviews so we cant backport it until it has passed.

    This is fixed for us in 5.3.3 p3, it was random but was occurring within couple of screen transitions.

    Thanks a lot guys, really appreciated..

    Unity 5.3.3p3 fixed for me too.
    But Unity 5.3.3p3 Resources.LoadAsync is too slow.On my case, use Unity 5.2.4 load async cost ~10s,but Unity 5.3.3p1 use more than 30s.

    Hi, we find some situation like crash at SyncDirtyElement is that you may have a infinite loop call in your code to refresh the UI elements.

    I couldn't create the same example project, since it only occurs in our main project. our bugly system have received the bug over 8000+ times during a test. it was very often, very upset! I will create a report if i can reproduce the bug.

    @boluns Hey, I know this is an outdated thread, but did you get any fix for what you wrote on Sep 15, 2017? I got the exact same problem in Unity 5.6.1
