Hi @HIKO992,
Welcome to Microsoft Q&A forum.
I completely understand your frustration regarding this issue. It is incredibly annoying when a core application like the Xbox app fails to launch, especially when you simply want to access your games and services. I can see that you have already put a significant amount of effort into troubleshooting this yourself, including updating Windows, resetting the app, and even attempting Safe Mode.
Based on your description, the app is launching to the splash screen and then immediately crashing or disappearing without generating an error code or a Task Manager process. Since you have already exhausted the standard troubleshooting steps and the issue persists, this indicates a deeper technical conflict or a specific bug that requires analysis beyond general Windows troubleshooting.
To ensure this is resolved effectively, this issue needs to be handled by the specialized Xbox Support Team. They possess deep, in-depth knowledge regarding the Xbox app architecture and have access to specific diagnostic workflows that can identify why the app is silently crashing. They are the best equipped to offer the right solution to help get this resolved for you as soon as possible.
You can contact them directly through the following support channel: Contact us | Xbox Support
Please note that as a community moderator, my limitations are to provide general guidance and information. I do not have the capability to access your device for remote troubleshooting, nor do I have the system access required to directly escalate technical tickets to the Xbox engineering team on your behalf.
I hope the specialized team can investigate this specific crash behavior and get your app running correctly soon.
Thank you for your patience and understanding throughout this process. Should you have any questions or need further assistance, feel free to reach out at any time.
