Describe the bug

The demo app from the Google Play Store (https://play.google.com/store/apps/details?id=io.getstream.video.android) crashes when backgrounding (minimizing/hiding) the app under specific conditions.

Steps to Reproduce:

1. In the Android device settings, configure the following for the demo app:
   • Battery: Set to "Restricted"
   • Picture-in-picture: Set to "Not allowed"

2. Open the demo app.

3. Tap "Start a New Call."

4. Tap "Start a test call."

5. After the call is launched and running, minimize (hide) the demo app.

6. Observe the app crash.

Observed Result:

The app crashes with the following exception:

E FATAL EXCEPTION: main

Additional Information:

• I also generated an APK (demo-app, developmentDebug) from the GitHub repository (https://github.com/GetStream/stream-video-android/tree/develop/demo-app) and was able to reproduce the crash.
• I also reproduced the crash, though less frequently, when Picture-in-picture was set to "Allowed".

Devices Tested:

• SM-A536E/DS, Android 15
• SM-S926B, Android 15
• SM-S921B, Android 15

Possible Cause:

I suspect the crash might be related to CallStyle.forOngoingCall
