Oculus Rift S Run in Background not working?

Hello,

If i remove and keep the oculus rift s headset aside while the Unity player (64-bit) is running and wear the headset again after 20-25 minutes, i only see a black screen with gazepointer and the whole Unity freezes. It takes 5 minutes or sometimes 10 minutes for the Oculus Rift S to go into resume mode. How do I fix this? I even wrote a script for running the app in background, it runs well but when I wear the HMD again, then it goes into freeze mode.

Code (CSharp):

1.      public bool debugLog = false;
2.      public bool runInBackgroundValue = true;
3.      void Awake () {
4.      }
5.      // Use this for initialization
6.      void Start () {
7.          Application.runInBackground = true;
8.      }
9.    
10.      // Update is called once per frame
11.      void Update () {
12.          if (debugLog) {
13.              runInBackgroundValue = Application.runInBackground;
14.          }
15.          if (!Application.runInBackground) {
16.              Application.runInBackground = true;
17.              if (debugLog) {
18.                  Debug.Log("Re-Setting Application.runInBackground to TRUE at: " + Time.time);
19.              }
20.          }
21.      }
