Oculus V37 OVRPlugin.dll not found issue

I am having an issue I believe is specific to the latest v37 release. I tried to update a v35 project to the new v37 and got the following error when starting up the project. I would downgrade to v35 again and have no issue. Each time I try v37 I get the following error on start up. Project crashes if I try to run. 

 

Failed to load OVRPlugin.dll
UnityEngine.Debug:LogError (object)
Unity.XR.Oculus.OculusLoader:EditorLoadOVRPlugin () (at Library/PackageCache/com.unity.xr.oculus@1.11.2/Runtime/OculusLoader.cs:237)
UnityEditor.EditorAssemblies:ProcessInitializeOnLoadMethodAttributes ()

 

I am using package manager and the oculus integration archive to get the v37 and v35 package. I have the Oculus XR Plugin and XR Plugin Management set up properly. I have tried with multiple unity versions 2021.2.10, 2020.3.22, 2021.2.5. I really want to try the interaction SDK but this strange issue is getting in my way.

Are any oculus team members able to comment on this issue? I am on the verge of buying a new PC as this is currently my only option to be able to properly use V37 integration. 

getting same error as you

This is fixed in the v38 integration which should be released relatively soon.  Thanks to everyone on this thread for bringing up the problem and helping us track down the issue.
