Hi there! I understand your Fairyland app shuts down right after the game starts. Let's try to figure this out together.

First, a couple of questions to get a clearer picture:
- Have you recently updated the app or your Windows 10 system?
- Does the app show any error message before closing?
- Are other apps running fine on your device?
- Have you tried restarting your computer already?

Meanwhile, here are a few troubleshooting steps we can start with:

1. Restart your computer if you haven't done so yet. This can clear temporary glitches.

2. Check for app updates: Open the app store or platform you use to get Fairyland and verify if there's an update available. Sometimes developers release patches for crashing issues.

3. Run the app as Administrator: Right-click on the Fairyland shortcut and select “Run as administrator.” This can resolve permission-related crashes.

4. Compatibility mode: Since you’re on Windows 10, right-click the app shortcut, choose Properties > Compatibility tab, and select “Run this program in compatibility mode for” Windows 8 or 7, then try launching again.

5. Update GPU drivers: Outdated or corrupted graphics drivers often cause games to crash. Check your device manager or visit your GPU manufacturer’s site to download the latest Windows 10 drivers.

6. Temporarily disable antivirus/firewall: Sometimes security software blocks game files mistakenly. Disable them briefly to test (remember to re-enable after).

7. Clear app cache or reinstall: If possible, clear the game's cache or local data, then uninstall and reinstall the game completely.

Since your device uses WebKit browsing and Windows 10, no specific browser-related issues should affect the game unless it's a web-based game. Could you confirm if Fairyland is a standalone app or runs through a browser?

Let me know how these steps go or if you notice any specific messages when the crash happens so I can assist you further!
