Hello SKY-HAGE,

Thank you for the update. To solve this, try using a mobile hotspot to see if the issue persists with a different connection. Here’s how you can do that:

1. Disconnect your mobile device from any Wi-Fi network.
   
2. Enable the hotspot feature on your mobile.
   
3. Connect your console to the mobile hotspot and attempt to load the game.

This is just a temporary workaround, but it will help us determine if there’s something on your current connection that may be causing the issue.

We appreciate your cooperation and look forward to your response!

Regards,
