With both the AR targets and Bluetooth beacons, ARIS does not yet handle any misconfigurations gently. Often creating is the result. I would check how you have the AR targets set up, both in Vuforia, down to which boxes are checked, and also in ARIS, which media types you are using. I recall earlier trying a GIF for the media that would play when viewing AR target. This would crash ARIS upon attempted view.
