Hi there! I’d be happy to help get your Startpage app running smoothly again. To better assist you, could you tell me a bit more about the crashes? For example, does the app crash immediately when you open it, or only after performing specific actions? Also, have you tried any steps to fix it so far?

Meanwhile, here’s a general step-by-step approach to try fixing crashing issues on Android 10 devices with WebKit:

1. Clear app cache and data: This removes temporary files that might be corrupted.
- Go to Settings > Apps > find Startpage.
- Tap Storage & cache.
- Select Clear Cache and then Clear Storage/Data.
- Restart the app.

2. Restart your device: This can clear temporary glitches affecting app performance.

3. Check for another update: Sometimes developers release quick patches after major updates.
- Open the Google Play Store.
- Search for Startpage.
- If an update is available, install it.

4. Reinstall the app: Uninstalling and reinstalling can fix files that didn’t install properly during the update.

5. Check for system updates: Ensure your Android 10 OS is fully updated, as OS bugs can sometimes affect apps.

If you have tried any of these already or the crashes happen in a specific circumstance (like opening the app or searching), please let me know. I can then suggest more tailored steps or check if there’s an ongoing known issue.

Are you satisfied with this starting point? Let me know how I can assist you further!
