Hi there! I understand that Real Racing 3 is getting stuck on the loading screen on your WebKit-based Android 10 device. Let's work through this together and see if we can get you back to racing.

To start, can you tell me if you have tried any steps already like restarting the device or closing and reopening the game?

In the meantime, here are some common and effective steps to try for this loading issue:

1. Restart Your Device: Sometimes just a device reboot helps clear temporary glitches.

2. Force Stop and Clear Cache of the Game:
- Go to your device's Settings > Apps > Real Racing 3.
- Tap on "Force Stop."
- Then go to Storage and tap "Clear Cache" (Don't clear data yet as you might lose progress if not saved).

3. Check Your Internet Connection:
- Try switching between Wi-Fi and mobile data.
- Sometimes, temporarily putting the device in airplane mode and then turning it off again refreshes network access.

4. Close Background Apps:
- Ensure no other apps are consuming too much memory or bandwidth by closing others running in the background.

5. Free Up Device Storage:
- Low storage can cause loading problems, so make sure you have enough free space.

6. Try Starting the Game in Airplane Mode:
- Launch the game without internet connection to bypass possible server sync issues.

7. Update or Reinstall the Game:
- Make sure RR3 is updated to the latest version.
- If nothing helps, back up your save account if possible, uninstall then reinstall the game.

If you have cloud saves enabled, sometimes the game gets stuck trying to sync corrupted cloud data, so starting offline can help confirm that.

If after trying these you’re still stuck, let me know which steps you tried, and if possible, share any error messages or additional details. We can dig deeper or explore other fixes from there.

Are you satisfied with starting with these steps? I’ll be here to help through each one.
