Left image distortion on Google VR for Android

Hi all, Does anyone have any idea why I’m getting the issue shown in the attached image?
Imgur
Essentially, the right hand side of the screen looks correct but the left side is totally distorted. In a previous build of this both sides look more or less correct, so I assume I must have inadvertently changed some important setting, or this must be an issue with the engine itself.
Any thoughts?
Thanks

Did you resolve the issue? I have the same problem currently.

I have the same error . Sometimes a project works fine, and suddenly the distortion begins.
