Hello, thank you for your answer, I found out that the problem still occurs without using the MRTK3 tool, when i Initialize XR sometimes Unity Crashes. Without the checkbox on "Compatibility mode" this problem still occurs. I tested this with a nearly empty unity project where only openXR is enabled.
The Crashlog from Unity has following line concerning the crash and my openXR settings:
i also have the full crash log attached.
Some tests showed, that this problem only occurs, when the Vive Business Streaming Application is installed and the XR Headset is initialized with SteamVR on the Computer. Using only for example the VIVE Pro did not result in Unity crashes. (But only if Vive Business Streaming is not installed)
Thanks in advance for your help!
