ue 4.13 empty project with plugin Google VR crashes on IOS

When launching an empty project on 4.13 my iphone it works fine. I get an app and it works i can see the ue world.

A soon as I enable the google vr plugin, the next launch ALWAYS crashes. I still get an app but crashes right after launch.

Launch log error:

WebKit Threading Violation - initial use of WebKit from a secondary thread.

Yes,the same to me.
Could anybody help us?

There appears to be a bug in 4.13.x’s implementation of the Google VR plugin for iOS. If you disable the plugin and re-deploy, the app will continue to work.
