Hello! I see you're having trouble with Disney Frozen Free Fall not starting properly on your device, showing the loading screen but then closing back to your phone's home screen. I want to help you get this fixed.

To help me guide you better, could you please confirm if you're playing this on a phone, tablet, or maybe on your Windows device through a browser? Also, have you tried any troubleshooting steps already, like restarting the device or closing the app completely?

Meanwhile, here are some general steps you can try for this kind of crash issue:

1. Force close the app: On your device, fully close the Frozen Free Fall app to ensure it's not running in the background and then try reopening it.
2. Restart your device: Power off your device completely, wait about a minute, then turn it back on.
3. Clear cache or temporary data: If possible, clear the app cache for Frozen Free Fall to remove any corrupted temporary files.
4. Check for updates: Make sure both your device's operating system and the Frozen Free Fall app are updated to their latest versions.
5. Stable internet connection: Ensure you have a reliable internet connection, as connectivity issues can prevent the app from loading properly.

Since you mentioned Windows 10 and WebKit environment, if you are running the game via a browser (like Safari or any WebKit-based browser), please try clearing your browser cache or try a different browser like Chrome or Edge to see if the problem persists.

Please try these out and let me know what happens or if you need help with any specific step!
