Hi! Sorry to hear your InStories Reels & Story Maker app closes right after you try to open it on your Android 10 device. Let’s try to get this sorted out.

First, can you tell me if this started happening recently? Also, have you tried any fixes yet, like restarting your phone or reinstalling the app?

In the meantime, here’s a step-by-step approach that usually helps with app crash issues:

1. Clear the app cache and data: Sometimes corrupted cache files cause crashes.
- Go to your device’s Settings > Apps or Applications > find InStories Reels & Story Maker.
- Tap Storage, then select Clear Cache first. Try opening the app again.
- If it still crashes, go back and tap Clear Data (this may log you out or reset app settings).

2. Restart your device: A fresh start can sometimes fix temporary glitches.

3. Check for app updates:
- Open the Google Play Store > Search for the app > If there’s an update available, install it.

4. Reinstall the app:
- Uninstall the app from your device.
- Reboot your phone.
- Go to the Play Store and install it again.

5. Check for system updates:
- Go to Settings > About phone > System updates and ensure your Android 10 is up to date.

6. Free up storage space: If your device is low on storage, apps can crash or malfunction. Make sure you have at least a few hundred MB free.

If you’ve tried all these already, or the app still crashes after these steps, there might be a compatibility issue or a bug in the app version for Android 10. In that case, I can help escalate this to the developers or check if there’s any ongoing outage or known bug affecting users.

Let me know which of these steps you've tried or if there's anything specific you noticed before the crashes started. That way, I can narrow things down better!

Are you satisfied with this initial plan, or do you want me to guide you through the steps?
