    We are having the same issue with 2021.3.7f1
    We still don't have any idea about what is causing it.
    We suspect that is happening when the app goes to background.

    This is an unfortunate race condition between Unity shutting down and and Java garbage collection happening at the same time.
    Please report a bug and do link this thread in the report!
    We do disable all proxies on background so that Java does not call into C# that is gone, but we have a race condition here.

    Hi @AdrianMesa ,
    Thanks for creating a bug ticket, but I don't have permission to access the portal that the ticket is in. I created an account with Unity3d - Altassian, but I guess I need some kind of authorization to view the ticket and the progress in it. Can you please either make the ticket public or give me access. I created the original post of this page. My email address is :
    sameer.raina@vincellstudios.com
    Thank you!

    Hey Aurimas, would you be so kind to point out some of the versions that have the issue resolved? I'm having trouble finding one. I'm currently on 2021.3.11f1 but the issue seems to still be present on that one.

    I tried Unity 2020.3.41 and the issue still exist.
    Also I can't see anything similar to this issue in release notes.
    The issue started to appear in my project after I downgraded Unity Advertisment from 4.3.0 to 4.2.1.

    Hey @AdrianMesa

    I also don't have access to Unity Bug reporting system in JIRA. I have new account.

    What I need to do to get access to Bug Reporting system?

    Good news, I got notified they reopened the issue.


    The internal verification for *IN-15979: [Android] Crash with Exception : java.util.concurrent.TimeoutException * against ** has failed our internal review.

    The request has been reopened and is awaiting further action.

    This is our top crash reported by Google Play Console. 9 out of 10 reports of a timeout exception indicate that one of our threads is stuck calling AndroidJavaProxy method.
    This exception is not related to an app shutdown. The crash happens only on Huawei devices. ANR helper thread from an AppCenter crash report indicates that:

    1) the Android activity is in a resumed (not paused or stopped) state when the crash is triggered;
    com.example.app.ANRDebug$Activity.resumed(ANRDebug.java:128)
    // Android activity is in a resumed state

    2) the app has been started less that a minute ago.

    Have been waiting updates on this as well, the issue persists in Unity 2021.3.17

    We have the similar analytics that 99% of the cases happen on Huawei devices

    Code (CSharp):

    We have the same top crash reported by Google Play Console. We are using Unity 2020.3.38f

    Code (CSharp):
    1. Exception java.util.concurrent.TimeoutException: com.unity3d.player.ReflectionHelper$1.finalize() timed out after 10 seconds
    2.   at com.unity3d.player.ReflectionHelper.nativeProxyFinalize
    3.   at com.unity3d.player.ReflectionHelper.b
    4.   at com.unity3d.player.ReflectionHelper$1.finalize
    5.   at java.lang.Daemons$FinalizerDaemon.doFinalize (Daemons.java:289)
    6.   at java.lang.Daemons$FinalizerDaemon.runInternal (Daemons.java:276)
    7.   at java.lang.Daemons$Daemon.run (Daemons.java:137)
    8.   at java.lang.Thread.run (Thread.java:929)
    It happens in the first 10 seconds of application start and affects only Huawei devices
    upload_2023-5-12_8-51-29.png

    This crash affects all our projects. We can reproduce this crash with this simple steps (on a Huawei device):
    1. Start the app
    2. Exit the app
    3. Repeat
    It occurs approximately in 1 out of 10 starts. After some research and patching of ReflectionHelper class we think that this crash caused by a deadlock in an internal JNI code. And we found that the frequency of this crash decreases significantly if we build our project with Android Studio using Export Project in Unity.

    Our crash rate for Huawei devices (the big drop is when an Android Studio build was released):
    upload_2023-5-12_9-31-56.png
    But the crash rate is still too high and we are waiting for a Unity fix

    We finally found the cause of the crashes on huawei devices. Updating to Unity 2020.3.46f1 or Unity 2021.3.19 or later did not resolve the issue in our case. Crashes disappeared but the application started to freeze at the same time it crashed before. We took a dump and realised that the main reason of freezes is Incremental GC. We disabled it in the project settings and the problem disappeared

    Hi guys,

    We are using Unity 2021.3.15. And this issue is the top 1 crash case which takes about 20% of total crash events in our game.
    @samrain_vincell
    Did you upgrade Unity to the version which mentioned by @kahyong_unity? Is the issue fixed?

    Thank you very much for your reply!
