Random crashes on HoloLens 2 related to OpenXR #11420

Closed Suddelnuppe closed 10 months ago

Suddelnuppe commented 1 year ago

Describe the bug

We experience random crashes on the HoloLens 2, that seem to originate from OpenXR. Updating both OpenXR packages in Unity didn't help. Neither did anything else we tried.

To reproduce

Unknown how to reproduce it. Seems to happen more often when the CPU is heavily used.

Expected behavior

No crashes

Your setup (please complete the following information)

Target platform (please complete the following information)

Additional context

Here is the stack trace from the crash dump.

@Suddelnuppe, are you able to share a crash dump file?

Also, can you please provide the versions of the OpenXR Plugin and the Microsoft Mixed Reality OpenXR Plugin?

Suddelnuppe commented 1 year ago

Hey @AMollis could you provide me with your work mail. I will gladly share what we have.

Hi @Suddelnuppe,

We appreciate your feedback and thank you for reporting this issue.

Microsoft Mixed Reality Toolkit version 2 (MRTK2) is currently in limited support. This means that Microsoft is only fixing high priority security issues. Unfortunately, this issue does not meet the necessary priority and will be closed. If you strongly feel that this issue deserves more attention, please open a new issue and explain why it is important.

Microsoft recommends that all new HoloLens 2 Unity applications use MRTK3 instead of MRTK2.

Please note that MRTK3 was released in August 2023. It features an all new architecture for developing rich mixed reality experiences and has a minimum requirement of Unity 2021.3 LTS. For more information about MRTK3, please visithttps://www.mixedrealitytoolkit.org.

Thank you for your continued support of the Mixed Reality Toolkit!
