Windows 10 Xbox App Sign in error (0x409) 0x80070005

Hi,

Corrupted profile data, an outdated version of the app, and software conflicts that occur when signing in are some of the factors that we have to take into consideration when troubleshooting issues with signing in to the Xbox app on Windows 10. Let's isolate
your concern by answering the following questions:

• Have you made any changes to your device or to your Xbox account before encountering this issue?
• Are you using the same Microsoft account to sign in to the Xbox app and your Windows 10 PC?
• Are you using an administrator user profile?
• Have you tried signing in to other built-in Windows 10 apps like the Store app to check if the same issue occurs?

Meanwhile, we suggest signing in to a different user profile. This can help determine if this is due to corrupted user data. Here are the steps:

• Press the Windows button on your device or keyboard, or select the
  Windows icon from the bottom-left corner of the main screen.
• Select your account name from the top-left corner of the menu, and then select
  Switch account.
• Sign in with an account other than the one you were using.
• Sign in to the Xbox app and check if the same issue occurs.
