As the title implies, I would like  to use Unity 2019 (version 2019.3.8f1) for my project, an application which would use hand tracking on the Vive Focus Plus.
However, a few seconds after I start the application on the headset, it suddenly freezes and crashes.
The same code, on a 2018 version of Unity, works perfectly.

I would like to know if anyone had encountered those issues with the Vive Focus Plus and handtracking on Unity 2019, and what steps you took if you did encounter this problem.
Have a good day ! 2020/05/13 11:37:57.041 22605 22799 Fatal libc /buildbot/src/googleplex-android/ndk-release-r20/external/libcxx/../../external/libcxxabi/src/abort_message.cpp:73: abort_message: assertion "terminating with uncaught exception of type cv::Exception: OpenCV(3.4.7) D:\Project\deeplearning\aristo\3rdparty\download\opencv-3.4.7\modules\core\src\alloc.cpp:72: error: (-4:Insufficient memory) Failed to allocate 32768 bytes in function 'OutOfMemoryError' So, I followed your advice for my next attempt, and I still get a crash about 10 seconds in. I built the app with IL2CPP targeting arm64.
The scene is a completely empty scene with only a FPS counter. This counter goes down as soon as the hands start showing up. You can try the latest 2019.3 version (which should be 2019.3.13 according to this page: https://unity3d.com/cn/get-unity/download/archive ) I would recommend using 2018.4 LTS version for stability. You to create a bug report to Unity to see if this can be fixed. Thanks a lot for your help, I switched to the 2019.1 version in the meantime, works like a charm on this one without any code adjustments.
I'll try to upgrade to 2019.3 later, and I created a bug report for Unity.

Thanks again !
