Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.

Please double check first if everything is up to date in your PC:

Open Settings, click Update and Security and then Windows Update;

Click Check for Updates;

Click the Download and Install Now option, if available (Install optional updates as well)

Also, check the Microsoft Store for any updates on the Xbox apps and its services and update everything too.

If everything is up to date or if the issue persists after the updates, do this:

Go to windows settings > apps > search for gaming services app > click on it and select advanced options.

After that, click repair and then reset

Then do the same for the Xbox app:

Go to windows settings > apps > search for Xbox app > click on it and select advanced options.

After that, click repair and then reset

Then try again.

If maybe that doesn't work, try these tutorials:

Or 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."

When i try to login to my xbox live on game pass pc it comes up with invalid JSON string how do i fix this?

Hi,

This seems like there is an issue with the installation of the Xbox App on your PC. Can you ensure you're on the latest version of the Xbox App by going to the Windows Store>Account Profile Icon>Downloads and updates. If there is no update available, can
you try to install the Xbox App (Beta) to see if you're able to use that version without any issues. This can also be found in the Windows Store by search.

Let us know!

Hello,

Check out this thread and see if the solution helps your issue: Invalid JSON string for xbox app - Microsoft Community

Essentially, there are two directories in "%userprofile%\AppData\Local\Packages\Microsoft.XboxIdentityProvider_cw5n1h2txyewy\AC\TokenBroker", Accounts and Cache. Each folder has one file in it. Delete them both, and try to log in to the xbox app again.

Thanks,
