    I'm working on a project with a group that requires the AWS SDK. In order to get the AWS SDK we had to update Unity from what we'd been using (2017.3.1f1) to a much newer version (2018.3.0f2). After updating Unity I'm unable to run the game, and I get the following errors:

    Could not load symbol ovrp_Initialize5 : The specified procedure could not be found.
    Could not load symbol ovrp_EndEye2 : The specified procedure could not be found.
    Could not load symbol ovrp_SetThreadPerformance : The specified procedure could not be found.
    Could not load symbol ovrp_AutoThreadScheduling : The specified procedure could not be found.
    Could not load symbol ovrp_GetInstanceExtensionsVk : The specified procedure could not be found.
    Could not load symbol ovrp_GetDeviceExtensionsVk : The specified procedure could not be found.
    Could not load symbol ovrp_SetAppAsymmetricFov : The specified procedure could not be found.

    And then a few others but you get the idea. They all revolve around not being able to find some sort of ovrp symbol. I've tried uninstalling and reinstalling the Oculus runtime on my computer, and I have the Oculus(Standalone) package installed. We are making this game in the oculus rift. I'm not sure if this is something I'm missing from unity or if I need some supplementary oculus software installed, please advise.

    I'm not sure what the problem is, but I'm also having this issue. I just upgraded from 2018.2.2 to 2018.3.0.

    I worked around it by turning it off temporarily: Tools -> Oculus -> Disable OVR Utilities Plugin. It should revert back to the built-in Oculus SDK. I'm not sure if all the features are supported in the built-in version, but it works in my case.

    I solved the issue, but I can't entirely remember how. I think I simply deleted all plugin files in my assets folder (had no idea they weren't necessary anymore), and re-imported the related packages in the package manager of Unity

    I have solved this issue
    Could not load symbol ovrp_GetNodeOrientationValid

    By importing "Oulus Integration" pkg again

    adb logcat Error message was:
    XR: Oculus could not be loaded: Failed to load symbol ovrp_GetNodeOrientationValid
