Bug JobQueue::WaitForJobGroupID(JobGroupID, JobQueue::JobQueueWorkStealMode)

Happens many times in my project:

Code (CSharp):

1. Crashed: Thread #1
2. SIGSEGV 0x0000000000000162
3. 0
4. libunity.so
5. JobQueue::WaitForJobGroupID(JobGroupID, JobQueue::JobQueueWorkStealMode)
6. 1
7. libunity.so
8. JobQueue::WaitForJobGroupID(JobGroupID, JobQueue::JobQueueWorkStealMode)

As I see in the logs it happens after "OnApplicationQuit".
Can't be reproduced on my device.
Unity 2020.3.42, 2021.3.14

 

Same here with Unity 2020.3.42f1. It only happens on iOS devices. The repro is quite simple, just close the app and after a few seconds, it will register a crash.

For me it happens on Android devices.

 

also happened on me. when upgrade unity to 2020.3.42f1 from 2020.3.3f1

Code (CSharp):

1. - (void)applicationWillTerminate:(UIApplication*)application
2. {
3.     ::printf("-> applicationWillTerminate()\n");
4.  
5.     // Only clean up if Unity has finished initializing, else the clean up process will crash,
6.     // this happens if the app is force closed immediately after opening it.
7.     if (_unityAppReady)
8.     {
9.         //UnityCleanup();
10.         UnityCleanupTrampoline();
11.     }
12. }

Code (CSharp):

1.   //UnityCleanup();

I don't know what's going to happen with this；
At least the crash doesn't happen anymore。

 

Has anyone come up with a fix/workaround for this besides commenting out the call to UnityCleanup? We're also seeing this issue.

 

Getting pretty similar problems on unity 2020.3.43f1, and can confirm on the exact same codebase it does not happen on 2020.3.25f1

 

Same issue for me on 2020.3.42f1 Is there any fix on next versions?

 

Facing same issue on 2020.3.44f1, any one got work around for this issue ?
