VR Uneral app is not getting closed

After Version77 update we started to have this issue: When unreal app 5.3 is started and then exited from the ingame menu's or web app menus then we get black screen and user remains stuck there. App does not close completely and goes back to oculus home area. 

 

Issue occurs from experience inbuilt menus but not occurring when the close is done from oculus overlay. 

 

Here is note from our developer:

"When the Core app is closed, it is actually completely closed by the system. However for some reason Meta fails to completely bring the previous app [oculus home] to the foreground. Clicking around (e.g. opening the list of apps on the Meta UI) wakes it up and brings back the user to the Oculus home.

Possibly the bug happens when:

We have a 2D foreground app (web app that launches unreal apps) starts another 3D app (VR Unreal app)

then removing the 3D app (VR experience) from the stack causes this."

 

We haven't observed this issue on v76. 

We are facing this issue on our all content experiences. Please help us on how to resolve this issue.
