ARKIT Face scripts + scene example broken/crashes on ios 11.4

Hey I'm trying to test the sloth face example or face mesh example scene doesn't open or goes to black on ios 11.4 curious if anyone else is having trouble with this?

I isolated the problem to this script and it opens unity logo then crashes or goes to black
I tried using the 12 beta and it still has problems
UnityARFaceMeshManager

I'm using 2018 and 11.4 and xcode 9.4 and the beta 3 build
