Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Nikitas

In order to assist you properly please answer the following questions :
Is this happening on PC or Xbox?
If you're on PC, are you on Windows 10 or 11?
Also, is this happening with the Xbox app / Microsoft store version or the steam version?
Is this happening only with FH4? If possible try using a different game (one that uses the Xbox sign in)
If you're on Xbox. Which one do you have?

And, which troubleshooting steps you have done so far to fix this problem besides log-in via browser?
In that way I can advise you different things or how to proceed

I couldnt do the 3 part so i cant do something

But thx for spending your time helping me

Thanks, Nikitas please try this:

First go to your default web browser and clear the history, cache and cookies via settings (if you don't use Microsoft Edge, do this on that browser as well)

After that try this (RainingRoses response):

"Try the following options for Windows 10/11:

1. Go to Credential Manager (https://support.microsoft.com/windows/accessing...) > Windows Credentials (not the Web option), select XblGrts|DeviceKey and remove.

2. Go to Settings > Accounts > Email & accounts. Select your account with the issue and verify that the ‘Apps need to ask me to use this account’ setting is enabled. This would especially help if you have multiple accounts as you would have the option to choose the correct account on startup, but you can always change it back to the automatic option if you prefer. You can also try to remove the account from here and re-add it later.

3. Follow this file path: C:\Users\[Your Username]AppData\Local\Packages\Microsoft.XboxIdentityProvider_cw5n1h2txyewy\AC\TokenBroker

Delete the Accounts and Cache folders, which will be deleted from the Xbox Identity Provider

Note that the highlighted code in this file path depends on your system so may vary.

If you don’t see a particular folder, then confirm there’s no search filters applied and select ‘show hidden items’, or you can just search for the folder in the search bar.

Restart your PC after trying the above steps, so that these properly take effect next time you sign in. It may also help to then reset and repair and/or uninstall and reinstall the Xbox apps where this error occurs."
