Cant sign into xbox app or game bar, error code 0x80048888

Yes, i am able to sign in with another computer.

Reinstall the Gaming Services app on your Windows 10/11 device:

Select the Search icon on the taskbar, type powershell, right-click on Windows PowerShell, and then select Run as administrator.

In Windows PowerShell, type the following command and press Enter:

get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers

In the same window, type the following command and press Enter:

start ms-windows-store://pdp/?productid=9MWPM2CQNLHN

Install the app on that page and select Yes when you receive the User Account Control (UAC) prompt.

Restart your device and try to install the game again.

I’ve tried a repair install from the .iso. Ultimately it’s not worth deleting all my data and starting over just to have a game pass subscription; I can get games from Steam just fine. Looking for a less radical solution that keeps everything intact

the steps above didn't work.

I found a line in a log file that seems to be the root of the issue:

2023-01-15T01:37:53Z E/XPAFTServer - GRPC: Handshake failed with fatal error SSL_ERROR_SSL: error:1000007d:SSL routines:OPENSSL_internal:CERTIFICATE_VERIFY_FAILED., sev=2 ['D:\a\_work\1\s\grpc\src\core\tsi\ssl_transport_security.cc' (1439)]

Any ideas?

I understand, Matt.

Is your Widows up to date with the latest update?

Have you tried creating a new account on your PC and seeing if it works and allows you to sign in on the other account?
