I'm using OVRCameraRig but it builds like a screen

Hello! Help me!
version:2019.4.9f1

Even if OVRCameraRig is added to the scene and built, the image cannot be seen 360 degrees and the image appears like a screen.

No error occurs, you can look around 360 degrees as usual when you build by simply placing an object in a new scene.

Please let me know if there are any changes to the settings that come to mind.

Thank you.
