    xbox invalid JSON string

    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!

    Invalid JSON string for xbox app

    Hello, how are you? My name is Mateus. I'm an Independent Advisor and I'll be glad to help you today.

    First, welcome to the Xbox community. I'm sorry you're having this problem.

    I ask that before trying which solution, check if your windows are using the latest version of the system, which in this case would be 21H1, for that follow the instructions below: Go to settings>system>about. If the system is not using the latest version of windows, update it by windows update.

    *If your computer updates are up to date, please try the solution below.

    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

    *I hope this can help you.
