Whenever opening Game Bar, closes immedietally

Reboot fixed it, sorry for wasting anyone's time.

Hi, sorry for the late reply, I've tried all of this, still no luck.

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Alysia

Please try this:

A. Reinstall the game bar via powershell command?
Right-click on the Start button and select Windows PowerShell (Admin) from the pop-up menu.

Copy and paste the following command in PowerShell and hit Enter to uninstall the Game Bar from your system.

Get-AppxPackage Microsoft.XboxGamingOverlay | Remove-AppxPackage

Now head over to Microsoft Store and search for Xbox Game Bar, install it and give it a new try

B. If maybe that doesn't work please delete the registry keys associated with the game bar :

Press Windows key+R then type regedit and press Enter.
Go to this path (expand the folders using the little ">")

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\GameDVR

Once there delete all the keys except (Default), restart your PC and try again

I have this, and when i press the xbox button the app open and close, together with the game bar

I tried all those steps multiple times, issue still persists.
