Hi! I understand that Monster Legends freezes right after you click the X on the ad just after opening the game. Let me help get this sorted out with you.

To better assist, could you tell me:
- Does this happen every time you open the game and close an ad, or just occasionally?
- Are you connected via Wi-Fi or mobile data?
- Have you tried closing and reopening the game or restarting your device?
- Do you happen to use any ad blockers or third-party apps that might interfere with ads?

In the meantime, here are some steps you can try to fix the freezing issue:

1. Check Your Internet Connection
Since ads require a stable connection, an unstable or slow internet might cause the game to freeze after closing ads. If you're on Wi-Fi, try restarting your router or switching to a different network.

2. Clear Browser Cache and Data
Your device default browser's cache (since you are playing on WebKit in Windows) might store corrupted data affecting ads. You can clear the cache and cookies from your browser settings.

3. Close Background Applications
Sometimes running many apps or browser tabs can cause performance issues. Close unnecessary apps running in the background to free up resources.

4. Disable Ad Blockers or VPNs
If you have any ad blockers or VPN services enabled, try disabling them as they can interfere with ad video playback and cause freezes.

5. Reinstall the Game
If the above steps don’t help, uninstall Monster Legends from your device and reinstall it fresh. This clears corrupted game data that may cause freezes.

6. Update Your Browser and Windows
Ensure your WebKit browser and Windows 10 are updated to their latest versions for best compatibility.

If the problem persists after these steps, please let me know, and I can guide you to look into advanced settings or connect you with our support team for further investigation.
