Unreal ARCore / ARTemplate - ARTemplate Black Screen after Stopping and Restarting ARMode

[PeterPansen]

Hey there! Hope I'm in the right section:

Test Project:

ARTemplate Project, no modifications. Deployment on an Android Device.

Unreal Version:

Ran into this problem in 4.25.4

Description:

If you run your Android application for the first time after deployment, ARSessions can get stuck. Start an ARSession, the Camera Feed will appear. Stop the ARSession, it will disappear. Start the ARSession again, black screen remains. No camera feed coming in. Quitting your application entirely and restarting it, solves this issue. But this, sadly, is not an option for all projects...

Steps to Reproduce:

Create a new ARTemplate Project for Android Deploy on your Android Phone Start Application (Bug only happens first time opening after deployment, keep that in mind) Start AR Mode (Camera Feed comes in) Stop AR Mode (Camera feed stops. Black screen. This is intended) Start AR Mode (Black Screen. No Camera Feed coming)

If I'm making an obvious mistake, let me know
