HandTracker access violation #10192

Closed cgsaxner closed 2 years ago

cgsaxner commented 3 years ago

Describe the bug

I have a custom C++/WinRT plugin which I include in an MRTK/Unity App for HoloLens2. When I run the App, after one or two minutes of moving my hands in front of the device, I get an 0xC0000005: Access violation reading location 0x00007FF93D839D31 error thrown in the Windows.Mirage.dll. Unfortunately, symbols for this .dll are not available. However, the call stack shows that the access violation is somehow caused by the OpenXR GetHandJointData() method:

Exception thrown at 0x00007FF91DF231D0 (Windows.Mirage.dll) in Image2FaceHL2.exe: 0xC0000005: Access violation reading location 0x00007FF93D839D31.

However, the same error also appears when using the WindowsXR Plugin instead of OpenXR. When disabling the "Hand Tracking" feature group and removing the "Microsoft Hand Interaction Profile" in the OpenXR Plugin management, the error disapperars, but of course, I cannot use hand interactions in my App then. When running the App in Debug mode, I can see that "InputDevices" keep getting created and removed, and it looks like this is somehow related to the error.

To reproduce

Steps to reproduce the behavior:

  1. Create Unity Project with MRTK and OpenXR or Windows XRSDK
  2. Add custom plugin to project
  3. Build & deploy to HoloLens 2
  4. Move hands in front of the device
  5. Access violation appears after one or two minutes

Expected behavior

No access violation happens when using hand tracking.

A couple things:

  1. Do you only hit this while debugging? Or in a release/master build as well without the debugger attached?
  2. We've made some improvements to our error handling in MR OpenXR 1.0.x releases, so it might be worth updating to the latest 1.0.3 release and seeing if anything changes. Your stack looks like the issue is at an even lower layer, but it could be worth trying.

Going to close this out for now. Please reopen if you're still seeing it!
