Hi there! I see you're experiencing crashes with Asphalt Legends when launching or playing through the Xbox app on your Windows 10 PC. Let’s work together to get this sorted out.

To start, could you please let me know if you see any error messages when the game crashes? Also, does it happen immediately when you start the game or after some gameplay? Knowing this will help me tailor the best steps for you.

In the meantime, here are some common troubleshooting steps that often help with game crashes in this situation:

1. Restart Your PC: This clears temporary files and frees up memory which can help if memory limitations are causing the crash.

2. Check for Updates: Make sure Windows 10, the Xbox app, and Asphalt Legends are all updated to their latest versions. Updates often contain fixes for bugs that might cause crashes.

3. Verify Game Files (if possible): Sometimes corrupted game files cause crashes. If the Xbox app or Microsoft Store allows, run a "repair" or "reset" for Asphalt Legends.

4. Clear Game Cache: Though more common for mobile, clearing cached data can sometimes help. On PC, you can try resetting the app via Windows Settings > Apps > Asphalt Legends > Advanced Options > Reset.

5. Run the Xbox App and Game as Administrator: Right-click both the Xbox app and Asphalt Legends shortcuts, select Properties > Compatibility > check "Run this program as an administrator." This can resolve permission issues.

6. Check Graphics Drivers: Ensure your PC’s graphics card drivers are up to date. Updated drivers can solve many crash issues.

7. Disable Background Apps: Other applications running in the background can conflict with the game. Close unnecessary programs while playing.

8. Run the Xbox Gaming Services Repair Tool: This tool fixes issues with Xbox services required by games from the Xbox app. You can find this tool online or through Xbox support.

If you’ve already tried any of these steps, please tell me which ones so I avoid repeating them and focus on other options.

Also, if you're comfortable sharing, what are your PC specs (especially GPU and RAM)? Sometimes, hardware limitations could contribute, and I can guide you accordingly.

Let me know how it goes, and we’ll take it from there!
