If an AR scene both takes load to load AND its Scene initialisation has many Actions to hide instances that may later be shown again, the timeout can be triggered easily. With the time out the user is presented with something like "could not load", but both the preview was rendered and if you tap, the scene properly loads into AR Quick Look. I suggest to both increase the seconds for the timeout trigger and consider to refactor the warning / error wording to account for several reasons.
