I Face Login Errors on Forza Horizon 5 for PS5 After Latest Update

I purchased Forza Horizon 5 for my PlayStation 5, expecting a smooth and enjoyable gaming experience. However, after the latest update, I can no longer access the game. Every time I try to launch it, I encounter a recurring error message saying, “You must sign in to your account,” even though I am already logged in.

I have tried multiple times to restart the console, log out, and log back into my account, but the error persists. This issue has made the game completely unplayable despite the significant amount of money I paid for it.

This has caused me both financial disappointment and emotional frustration, as I am unable to access a product I legally purchased. I expect the developer or PlayStation support to address this login error immediately.

I explicitly request a permanent technical fix for this issue or a full refund if the game cannot be made playable.
