Occasional crash/shutdown when awaking from idle on Quest

Hello,

We have a random either crash or shutdown on Quest2, I’m not 100% certain. The issue is that when you take off your headset and it enters standby (when the sensor is away from the face), every so often when you put the headset back on we find ourselves in the quest home lobby instead of the game, meaning the game either crashed or shutdown. Attached is the log from the issue, I’m assuming this is a crash because of how the log seems to cut off a the end, but things are just weird enough that I’m not certain this is a crash.

The main variable here is how long we leave the game in standby. We’ve only seen this if we leave the headset in standby for 10 minutes and longer, and our game bounces back to mainmenu world lobby after 8 minutes, so a level load might be related. Again, the issue is very infrequent, and the lack of reliable repro steps is making investigation difficult.

I’m aware that this question will likely fall outside of the scope of Unreal support, but documentation on UE+Quest+IdleStandby is limited and I’m hoping you might have some insights into the issue.

Best Regards

Are you saying that you have logic that calls Open Level after 8 minutes? Does the crash/shutdown happen if you don’t call that? It would be difficult for us to track this down unless we know what the repro steps are, so any details you can share that helps us reproduce it would be helpful, thanks!

Sorry, the best I can say is that there is likely an Open Level call. We don’t have reliable repro steps and haven’t been able to catch it in a controlled environment because of how infrequently it happens. Because its Android Quest the logs are cutoff / incomplete when the crash occurs.

I would suggest you remove the Open Level call(s), and continue to test the application without them to see if that indeed is the culprit. I unfortunately don’t know of anything specific in this area that is known to be broken, or heard of any other similar reports.
