OVR Plugin failure for detection space / importing Room-Data into Unity

[florian.buchholz.1988]

Since you, @MetaQuestSupport, are clearly ignoring my post in the Unity VR Developer forum and my direct messages as well, I will ask this here again:

I want to use the Room-Setup feature from the Quest 3 in Unity in Mixed Reality.

I get an error for importing the transform-data for the gameobjects of the Quest 3-defined room in Unity. All of the walls and room objects are at (0,0,0) with no additional rotation and I get this error:

[OVRPlugin] [XRCMD][failure] [XR_ERROR_HANDLE_INVALID]: xrLocateSpace(*(XrSpace*)space, baseSpace, ToXrTime(GetTimeInSeconds()), &spaceLocation), arvr\projects\integrations\OVRPlugin\Src\Util\CompositorOpenXR.cpp:11831 (arvr\projects\integrations\OVRPlugin\Src\Util\CompositorOpenXR.h:302)

It seems to be an issue that is unique to my PC, but I can not figure out why and where the issue is.
We tried the same scene and multiple other with the room model or the new MR Utility Kit in it, and we don't know what is different in my system.

We already tried uninstalling all of Unity, Meta and Oculus desktop and cleaning the registry / Appdata.

It works on different PCs with the same Headset, it also works on different PCs when I am logged in into Unity and Oculus Desktop.

We also switched out the Cable, the Headset and the USB-C port.

We also deactivated all of Windows Defender and disconnected the PC from the Web.

Everything needed in Unity is activated, as well as Developermode on the Quest and in Oculus Desktop. This should not be the issue, since the same project works on other PCs.

The Setup is:
13th Gen Intel(R) Core(TM) i9-13900K 3.00 GHz
32.0 GB DDR5
Nvidia RTX4090

Windows 10 Pro
Version 22H2
OS build 19045.3930

FYI: I reinstalled Windows. The bug is gone now, but I did not figure out the reason. My best guess is right now the Meta Quest Developer Hub and some settings there.

It's the HTC Vive Business Streaming software! No wonder nobody else has this issue, because who would work with HTC and Meta at the same time? But right after installing the "Vive Business Streaming", I get the same issue, so it seems like it interferes with the OVR / OpenXR - version / level / software / sdk / whatever on a fundementally level.

The reason I installed that software a while ago was because I wanted to use the new Ultimate Trackers in my application, but on a different system, without any HTC-Headset. Who would have thought, that this software also interferes with OVR...

Uninstalling THAT software and restarting resolves the issue for me

I'm having this issue right now and I do not have Vive business software installed (never have), so it seems like there's a deeper underlying issue here 

[florian.buchholz.1988]

What about the meta quest developer hub? I haven't installed that yet and it might also interfere with it. Did the problem suddenly occur or after updating or installing new software? I would really try to find a permanent fix for that.

Unfortunately this is my first project since 2017 in Unity, following the most recent tutorial I could find on YouTube for setting up the MR toolkit in unity.

I do not the the developer hub installed, didn't even know it existed - So thanks! I'm going to try it out later 😃

[florian.buchholz.1988]

I don't think installing it is going to solve the issue in your case, at least it didn't in mine. I thought it might be the reason for the error on your end. Nevertheless, enjoy the tool, it's quite useful, especially because you need it for uploading your apps to the quest store, but also for streaming, ADB and so on.

Keep me posted if you find out what the error caused on your PC!

Thank you so much for this! ✊

Thank you so much! This helped me solve my problem in MR development.

Thank you so much!!! I was so confused. I used to develop for the HTC Vive too, but I didn't have that specific software you mentioned. I still went ahead and deleted every single possible HTC Vive related software on my PC, and then it just magically worked. This was so helpful. Meta/Unity definitely needs to fix this somehow. I would have never been able to figure out it's something to do with Vive software.
