Sorry to say I can't replicate.
Tried just now on a game from a while back. It worked well. No crash on recognition or tap after. I'm on a iPhone 6s, iOS 11.4.1, and most recent App Store version of ARIS. I wonder if something in the creation stage has either changed or is wrong? Did you pick up on the parameter of 500(?) instead of the default 1 you need to put in to each target in vuforia? What media type are you handing off to? back in the day I had this problem with images other than jpeg, but that was fixed a while back. not that it couldn't be broken again.
