Unable to start Oculus XR Plugin

    In both 2019.3 and 2019.4, after installing the XR manager and the Oculus package and placing an XR Rig in the scene, I get this

    and the headset doesn't work in Unity.

    This happens in a new scene in a new blank project, in both 3D and HDRP.
    The project I need to migrate to VR is in 2019.3 so I didn't try older versions.
    The headset works in other apps.
    Did anyone experience anything like this?

    Hey there Bogheorghiu,

    a couple of quick questions:
    • What version of XR Management are you using?
    • What version of 
      xr.sdk.oculus
      are you using?
    • I'm assuming you're running on Windows, but could you confirm that?
    Looking at that screenshot, my first reaction is that potentially the 
    xr.sdk.oculus
    dll's are corrupt in your install? What happens if you uninstall/reinstall the 
    xr.sdk.oculus
    package?

    Additionally, can we see the callstack on the highlighted bug? That might give us further insight.

    I have the same issue...

    Unable to start Oculus XR Plugin.
    UnityEngine.Debug:LogError(Object)
    Unity.XR.Oculus.OculusLoader:Initialize() (at Library/PackageCache/com.unity.xr.oculus@1.3.4/Runtime/OculusLoader.cs:111)
    UnityEngine.XR.Management.XRGeneralSettings:AttemptInitializeXRSDKOnLoad() (at Library/PackageCache/com.unity.xr.management@3.2.12/Runtime/XRGeneralSettings.cs:148)

    It happens event when I start a new project.
    I use Oculus Quest via Link.

    Same here. 2019.4.1f1 on Windows. Oculus app installed and working.
    Oculus XR Plugin = 1.3.4
    XR Plugin Management = 3.2.12

    Also tried some older packages versions, same error. Bummer, can't get any VR working with the last Unity versions, neither Windows, nor macOS.

    You guys need to get back in the game, several days we are stuck with all those errors in the last versions.

    I am having the exact same error messages after converting over to the Universal RP. I have not seen these three errors in succession before.
    Unity 2019.3.13f1
    Oculus XR Plugin = 1.3.4
    XR Plugin Management = 3.2.12

    Apparently, the message is gone when I switched back on the 3.2.10 of the XR Plugin Management (but it's strange since I'm pretty sure having already tried to switch them back to an older version a few days back). Also using the URP.

    Make sure your Oculus device is working and if it's Oculus Quest it's in Link mode. Having Oculus app on is not enough. This fixed the issue for me (Unity 2019.4.1f1).
