Vive Business Streaming is interfering with Unity Application on a fundemental level

[FlorianFIT]

Dear Vive Developer Team,
it took me two weeks of work to figure out, that by installing the "Vive Business Streaming" software, I get an error in a totally unrelated unity-project with my Meta Quest 3.

While using the Feature of getting the room-data in from the Quest 3 into Unity 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)

OVRManager:Update () (at ./Library/PackageCache/com.meta.xr.sdk.core@60.0.0/Scripts/OVRManager.cs:2723)

This results into all the objects of the digital room not having any Transform-Data.

It took me two weeks and a complete reinstallation of Windows 10 to figure out that the moment I install Vive Business Streaming, this error occurs! I really did my homework, after every install of any software, checking if the test-project still works.

It's your software. Thanks for nothing.

The reason I installed the software is, because I want to use the Ultimate Tracker. Now I have to do this on a totally seperate machine, until you fix that issue.

Sincerely,

I had the same problem. Uninstalling "Vive Business Streaming" fixed this XR_ERROR_HANDLE_INVALID issue.

But also many other issues like "DllNotFoundException" errors I've been having for a long time. When pressing "play" button in Unity Editor + Quest 2 via Link.

My workaround was to
Press Play button in non-VR, Stop. connect Quest Link, then Press Play button to play in VR.
