If you call the "GetCameraImage" function rapidly ~10 times, it causes the ARKit camera feed to stop updating. Waiting for awhile or tapping some more seems to bring it back.
Tested on macOS High Sierra with xcode 10.1 on ios 12
1) Run UE4.20.3 that has been downloaded via Epic Games Launcher.
2) Create a new project by selecting the HandheldAR template with the Target Hardware set to Mobile / Tablet.
3) Enable the AppleARKit plugin.
4) Add to BP_ARPawn the Blueprint that I provided as an image on this thread.
5) Configure the settings for iOS packages.
6) Create a package and run the application.
7) After AR starts, tap the screen ten times or so.
8) Confirm the camera no longer updates.
