Workaround: In AudioMixerSourceManager FlushCommandQueue() function, Replace both Wait() calls with Wait(1000)
This does not occur with some previously packaged First Person templates that were on the device still namely one from //UE4/Dev-VR 4.21.0 @CL 4277723
It also does not occur with other apps on the devices.
This occurs with the Oculus Go and Quest.
It also occurs with a package of QAGame running Stereo Layers map from 4.22 although that must have been a Github build as there is no CL present in the logs for that project.
Results: The HMD will display a black screen until you try to interact with it with a controller or turn the display off and on which will prompt the "App is Unresponsive" message to appear.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-72585 in the post.
