Hi,Welcome to the Oculus Forums.What version of Unity are you utilizing for development?Please consult the Unity compatibility chart below to make sure that you are using the proper releases:https://developer3.oculus.com/documentation/game-engines/latest/concepts/unity-sdk-version-compatibility/
Is your engine proprietary or freely available? I'm trying to get more information to help address this issue. Seeing as the SDK release you reference upgrading from is much older than those currently available, it could be any number of issues causing this on your end.
