Question

Xbox App completely fails to launch on Windows 10 - already tried Gaming Services reset

Kerem Can Baş 0

Hi,

I'm running a custom Windows 10 build (dual-boot setup) and my Xbox app has suddenly stopped launching out of the blue. It was running perfectly fine. Now, when I click the app, nothing happens, there is no splash screen, no loading icon, and no error code. It just silently fails to launch.

I have already done extensive troubleshooting. Here is exactly what I have tried so far with zero success:

App Repair & Reset: Navigated to Settings > Apps & Features > Xbox and ran both the Repair and Reset functions.

Nuked and Reinstalled Gaming Services: Ran an elevated PowerShell prompt and executed Get-AppxPackage *gamingservices* -allusers | remove-appxpackage -allusers, followed by forcing the reinstall from the Microsoft Store using the ms-windows-store://pdp/?productid=9MWPM2CQNLHN command.

Cleared Microsoft Store Cache: Ran wsreset.exe successfully.
Windows Updates: Checked for any pending Windows 10 patches or Store hotfixes.

Here are the error details from the crash logs:

Exception Code: 0xc0000409

Faulting Module Name: ucrtbase.dll

Faulting Application Name: XboxPcAppCE.exe

Event Name: MoBEX

System Specs/Details:

OS: Windows 10 (Custom build, Dual-boot setup)

Symptom: Xbox app fails to execute entirely; silent crash in the background.

Since I have already rebuilt the Gaming Services dependencies, does anyone know if there is a specific Event Viewer log I can check to see exactly what process is killing the launch? Are there any deep registry fixes for this specific silent failure?

Hi people!

I want to address that I have resolved the issue by moving to Windows 11 from Windows 10.

I recently changed my motherboard and that may have caused some licensing problems with Windows 10. This seems to be what caused the problem from what I can tell but I might be wrong.

Hello Kerem Can Baş,

Welcome to Microsoft Q&A forum.

0xc0000409 is a stack buffer overrun error, this usually caused by a corrupted Xbox package or Windows profile corruption. Before we proceed further, may I know if you have tried to uninstall the Xbox apps and reinstall it yet?

Additionally, can you please try to create a new user profile to see how it goes there?

I'm waiting for your reply.

Hello Carl,

Thank you for reaching out.

I have tried uninstalling and installing xbox app but it did not solve the issue.

Although I changed my motherboard recently and I think that has caused some windows 10 licensing problems. I have switched to windows 11 and it works fine now.

Thank you for your assistance.
