Hi! I see you're having trouble with the VolcanoEbook app crashing on your WebKit browser with Android 10. Let's work through this together so you can get back to enjoying your reading.

Could you please tell me a bit more about when the app crashes? For example, does it crash immediately on opening, during reading, or at some other specific point? Also, have you tried any fixes so far, like restarting your device or reinstalling the app?

While you share that, here are a few straightforward steps we can try to resolve the crashing:

1. Clear Cache and Data:
- Go to your device Settings > Apps > VolcanoEbook.
- Tap on Storage.
- Clear Cache first. Then, if the problem persists, clear Data. (Note: Clearing Data may require you to log in again and could remove saved preferences.)

2. Update the App:
- Check if there is an update available for VolcanoEbook in the Google Play Store or the app source you used. An outdated version can cause crashes.

3. Reinstall the App:
- Uninstall VolcanoEbook.
- Restart your device.
- Then reinstall the latest version of the app.

4. Check for System Updates:
- Go to Settings > System > Software update.
- Ensure your Android 10 has the latest patches as system updates can improve compatibility.

If these steps don't do the trick, there might be an issue related to your account or device compatibility that requires a deeper look.

Let me know how it goes after trying these steps or if you have any other details about the crash behavior. We'll get this sorted out! Are you able to try these steps now?
