Apple rejected app due to crash but I cannot reproduce

I am using the GoogleVR plugin with UE4 4.20 on a windows PC and remote compiling on a mac. I have tested on 6 different iPhones. Model type: SE, 7 and X.

The app is working as expected and I cannot reproduce the crash.

I’ve attached 2 crash logs, does anyone have any idea what could be causing this?link text
