Hi there! I understand you're seeing Asphalt Legends start up but then get stuck on the loading screen after launching a race, and sometimes the race begins but with glitches. Let’s try to get this sorted out together.

To start, could you tell me if this happens with every race or just certain ones? Also, have you noticed if it occurs only after a recent update or has it been like this for a while? Knowing these details will help me guide you better.

Meanwhile, here are some initial steps you can try on your Windows 10 WebKit setup:

1. Close Background Apps: Sometimes other apps using high CPU or memory can interfere. Open Task Manager (Ctrl + Shift + Esc), check if any processes are using a lot of resources, and close unnecessary ones.

2. Restart the Game and PC: A fresh start can clear temporary glitches. Make sure to fully exit Asphalt Legends before restarting your PC.

3. Clear Cache/Data: Go to Windows Settings > Apps > Apps & features > Asphalt Legends > Advanced Options. Then try the “Reset” option. This will clear the app cache and data, which might be causing loading issues.

4. Check for Updates: Make sure both your Windows OS and Asphalt Legends app are fully updated.

5. Graphics Driver Update: Sometimes glitches come from outdated or faulty graphics drivers. You can update your Windows 10 graphics drivers via Device Manager or the GPU manufacturer’s website.

If you’ve tried these already or the problem persists, please let me know which steps you have done so I can suggest deeper troubleshooting specifically tailored to your setup.

Does that sound good? Let me know how it goes or if you want help with any specific step!
