Xbox Game Pass game stuck on sync (Neither of the available solutions are working)

Hello DenisLovász, My name is David. I am an independent advisor, happy to help you today.

I understand you're having issues syncing data in Forza Horizon 5 via Xbox Game Pass. Here are some additional steps you could take to solve this problem:

End the gamingservices.exe process: Open the Task Manager, go to the “Details” section and look for the “gamingservices.exe” process. Finish this task, then it should restart after a few seconds.
Make sure your Internet connection is stable.
Repair and reset the Xbox app and Gaming Services: Go to Settings > Apps > Apps & features. Select Gaming Services, then click Advanced Options. Click the reset button.
Restart Xbox-related services.
Check if all Xbox Game Pass games get stuck when launching.
Check if your Xbox app is set up for offline gaming.

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.

Best regards.

No. Neither EA Play or Game Pass are available for the 360.

Ive tried reinstalling the game and restarting my xbox and neither worked :/ any other solutions?

After looking over both of those links, neither lead me to a solution, and both include everything I've already attempted. It just seems like nothing has changed to fix this issue on Microsoft's side, and no fix or solution has arisen on the consumer's side that I've been able to find. I guess I'm inevitably stuck having to fully purchase both games through the Launcher at full price since any time I click "Play with Game Pass for PC" it automatically takes me to the webpage to subscribe to Game Pass for PC, even though I have Ultimate. Neither version through the Launcher gives me a button to just play, only "Buy Now", or "Play Demo".

Neither of my two controllers would manually sync either. Thanks for reminding me about the USB cable. Your solution worked like a charm for me too. Cheers.
