GearVR/Oculus Splash Screen crashes into black on "Open Level" UE 4.18.3

I’m using Unreal Engine 4.18.3. - Target Platform is GearVR / Android.
The App/Game crashes into a permanent black screen after the SplashScreen.
The First Map/Level (Default Map) works, but when we try to open the next Map via the “Open Level” Node the App gets stuck into black.

Is there a way to fix it? We tried the Oculus Splash Screen Nodes, Splash Screen Option in the OculusVR Tab (Project Settings > Plugins) and to add it manually in the DefaultEngine.ini File.
Nothing works.

Does anybody has a workaround for this “known” issue?

Thanks in advance,

Obsolutely the same problem. And I didnt find out any solution yet…

You should probably also check this with Oculus in their Unreal branch forum:
