ARKit, iPhone 11 Pro, "Could not transform image" issue

I noticed an issue when testing my AR software on my iPhone 11 Pro when holding it horizontally to the right - Xcode's console starts printing this error message over and over.

Code Block 
[Technique] Could not transform image.

I created a new Xcode project with the ARKit template. Made no changes. Just built it and ran it on my iPhone 11 Pro (connected over USB)

Phone vertical - no problem
Phone horizontal to the left - no problem
Phone horizontal to the right - the above error message repeated

Any idea (1) why this occurring? And (2) why it occurs when the phone is horizontal to the right but not the left?

Any known work-arounds (besides "Don't hold it to the right")?
