    We noticed this crash after release in app store with unity 2018.1.7f1. It wasn't noticed in debug builds. This is stacktrace.

    Often crashes in MonoManager::GetScriptingClass indicate something is wrong with engine code stripping. If you get to a point where you can reproduce this issue, maybe try it without engine code stripping enabled (if it is enabled).

    Otherwise, I'm not sure about the cause of the issue.

    Note that main thread is calling il2cpp::vm::Runtime::Shutdown while crashed thread is trying to log exception. May be this is cause of the crash?

    Ahh, that is interesting, I did not notice that. Some code must be throwing an exception during shutdown. Maybe there is an order of operations problem here.

    Is this something you have been able to reproduce locally?

    Hi, JoshPeterson

    Thanks for you advice. I have reported a but to Unity, this is the reply from Unity.

    Thank you for reporting this issue.

    Unfortunately, we do not support builds or Unity versions of 2018.1 and 2018.2 anymore. Please upgrade your Unity version and if the issue is still present please attach a minimal project which reproduces the issue with the steps how to reproduce.

    If you have any further questions feel free to ask.

    Best regards,
    Vita
    Unity QA Team

    Did this get resolved somehow? We've been seeing this error on Crashlytics for a long time, but I haven't been able to reproduce the crash myself.

    I don't believe that it was resolved yet, sorry. We don't have a reproducible case for it yet.

    No, we've not had a reproducible test case for this issue, so we've not been able to correct it. If you can submit a bug report with a test case, I would appreciate it.

    I've just merged a possible fix for this crash in the 2019.1.1f1 release of Unity. The same fix will be coming to the 2018.3 and 2019.2 release streams soon as well.

    We've not been able to reproduce this crash, so the fix is more of a defensive change, and we cannot be certain that it corrects this issue. So I'd love to hear any feedback from those who can try it once it is available. Thanks!

    We will back port this change to 2017.4. I expect it to be in the 2017.4.28 Unity release.

    We don't have an issue ID for this problem, as we never had a reproducible bug report for it. The possible fix I mentioned above is (or will be) in the following Unity versions:

    2017.4.28f1
    2018.4.0f1
    2019.1.1f1
    2019.2.0b3
    2019.3.0a5

    Thanks Josh. My game is built with Unity 2018.4.0f1 and Apple reported the following user traceback on it, which is different than the one @cruelbob reported to start this thread, but also is in GetScriptingClass() during shutdown, so it looks like the possible fix doesn't address all cases, unfortunately:

    Do you happen to have the call stacks from all threads?

    Thanks! This does look slightly different than the crash listed above. Is this something you can reproduce? It feels like we should be a new bug report for this issue.

    This crash is intermittently reported to me through Apple, and I have not personally been able to reproduce it.

    As a developer myself, I fully appreciate the value of reproducibility for fixing bugs, but one of my peeves with Unity as a company is that your QA department just closes any report than doesn't have a reproducible project attached (at least in my experience).

    Isn't the stack trace itself at least quite useful? Other than heap corruption issues, it can practically pinpoint the failure point. I wish there were a way to just report the stack traces (other than this forum) that didn't go through the QA department to be closed out immediately.

    Yeah, I understand. With the number of bugs our QA team handles, reproducibility is usually necessary, because we just don't have the bandwidth to track down the cause of intermittent bugs like this. However, I would like us to improve in our handling of intermittent bugs. We don't have a great process for doing that now.

    In this case, I think it is worthwhile to submit a bug report with the stack traces from all threads. Once it is submitted, let me know the case number, and I'll update the case with some notes for our QA team to indicate that we want to investigate this even without a reproducible test case.

    Thanks Josh. Before I submit another bug report, can you take a look at 1145982? That's what I filed for this issue initially (that was closed by QA) when it happened with Unity 2018.3.11f1. That report has the full stack trace attached. I think it's the same issue, but if not, let me know here and I'll file a new issue and get you the case number for it.

    I've re-opened the bug report. We will investigate it more. I can't promise a fix, but the stack trace from all threads should be helpful.

    We just released an update to our game, updating from 2018.2.12 to 2019.1.1, and have started seeing this crash on shutdown in Crashlytics as well. Would it be helpful to have more stack traces? They do look very similar to the ones already posted.

    These stack traces all look pretty similar. I'm suspecting now that our proposed change did not actually correct the original problem here.

    Can anyone confirm that they have stopped seeing a similar crash with the versions I listed above? Also, if anyone is able to reproduce this locally with some case, that would be a great help.

    Hi!

    Here in our application, we download an asset bundle hosted in our servers and through image recognition we start a new scene that is inside the bundle we just have downloaded. The particular scene we are trying to open has some functionalities made with the Bolt asset, and just with this scene we catch this error, but it occurs 80% of the times we try to start this scene, so I think Bolt is not the problem. All other scenes without bolt features works pretty well

    I'm sending you the crash report that I got whenever this errors occurs.

    I tested using the following unity versions:
    • 2018.3.2f1
    • 2019.1.1f1
    • 2019.1.4f1
    Let me know if you need some other info

    Kind regards

    I don't see any symbols in these call stacks, so it is difficult to tell if this crash is related to the issue being discussed in this thread, unfortunately.

    Right... Is there any other way to get another stacktrace? By xcode maybe? If not, should I open another thread to discuss this error?

    I read that this exception could be related to an wide range of things, so I thought this could be related

    Sorry, I was not trying minimize your issue, I just wanted to clarify that it looks different.

    If this is something you can reproduce locally, then catching it in Xcode will provide the most useful information. If you can get better debug information, then it is probably worth a new forum thread.

    We have this issue on 2018.4.3f1 as well

    Based on our event logs, the player does not manage to properly initialize the game at this point and all of our custom data is empty at this point.
    We use Crashlytics (fabric) for issue reporting and have not migrated to FireBase (yet)

    Interesting - the crash indicates that the application is shutting down. Do you mean that the game is actually starting, then immediately shutting down for some reason?

    Yes, that's what it is indicating.
    The game has not managed to get basic events logged into the Crashlytics events such as AppStart.

    Unfortunately we do not have a local repro yet but this is one of our most common native crashes on iOS.

    I managed to repro the crash (on 2018.4.1f1).
    I did this by continuous re-starts of the application.
    As the app was restarting I force closed it immediately.
    I managed to get this to happen 3 times within a minute by varying the shutdown time.

    My suspicion is now that Unity hasn't managed load something it's trying to shut down.

    No, unfortunately we don't have a case where this is reproducible yet. If you have one, please submit a bug report. Thanks!

    It looks like we do have a reproducible test case for this issue, see https://issuetracker.unity3d.com/issues/ios-crash-during-shutdown

    We've not come up with a solution yet, but at least in the test case we have, the problem is caused by calls into the Unity API (specifically Debug.LogException in this case, but maybe others as well), during the shutdown process.

    So, for anyone experiencing this, it might be worth checking your code which runs on non-main threads. Does it call into the Unity API? If so, could that call happen while the player is shutting down? In general, the Unity API is not thread safe, so calls to it should only occur on the main thread. However, it is really unsafe to make calls on the background thread during shutdown.

    We will see if we can do something to avoid a crash in this case, but it may not be possible for the Unity API to call succeed in these conditions.

    But Unity throws an exception if you attempt to call the Unity API on a non-main thread, right?

    For many APIs, that is true, but not for all, unfortunately. Only APIs that end up calling to the main engine code will throw an exception.

    Also note that even throwing a managed exception during shutdown might be a problem. The .NET VM runtime is in the process of shutting down, so it may not be able to properly through an exception.

    @JoshPeterson Do you know if it would still be unsafe to call Debug.Log from a non-main thread when Debug.unityLogger.logEnabled == false? That's the scenario I have in my production code where I get this crash.
