Hi! I understand that when you try to play Jujutsu Kaisen Phantom Parade on your Windows 10 device using WebKit, the game stops responding after you press play, although the music keeps playing. Let's get this sorted out.

To start, could you let me know if you've tried any troubleshooting steps already? For example, have you restarted the game, your PC, or checked for updates to the game or your system? That will help me avoid repeating any steps.

Meanwhile, here’s a basic plan to tackle this issue:

1. Check for PC and Game Updates
- Make sure your Windows 10 is fully updated (sometimes updates can affect game performance).
- Look for updates or patches for Jujutsu Kaisen Phantom Parade and install them.

2. Disable Background Applications
- Close unnecessary programs that might interfere with the game, as sometimes other software can conflict with game loading.

3. Check Game Files or Reinstall
- If you installed the game via a client or platform, use its option to verify integrity of game files.
- If no such option, uninstall and reinstall the game to ensure no corrupted files are causing the freeze.

4. Run as Administrator and Compatibility Mode
- Right-click the game executable or shortcut, choose “Run as Administrator.”
- Additionally, try running it in Windows 8 compatibility mode to see if that helps.

5. Graphics Drivers and DirectX
- Update your graphics card drivers (NVIDIA, AMD, or Intel) to the latest version.
- Ensure that DirectX is updated on your machine, as this supports many game graphics features.

6. Check for Known Issues
- There was mention of a Windows 10 update causing issues for PC clients of this game before. If your problem started after a recent Windows update, try rolling back the update or checking for patches addressing it1.

Does the game freeze right after you press play every time, or does it ever get past the loading screen? Let me know, and if you’ve done any of these steps, so we can go deeper if necessary.
