How to fix error dxgi-error-session-disconnected in Windows 11

Solution Steps

1. 1 Press Windows key + R, type 'sysdm.cpl', and press Enter. Go to the 'Remote' tab and uncheck 'Allow Remote Assistance connections to this computer'. If you're using remote desktop, this might not be possible, but for local gaming, it prevents unexpected disconnections.
2. 2 Press Windows key + I to open Settings. Go to System → Display and set your game to 'Windowed' or 'Borderless' mode instead of 'Fullscreen'. This allows the game to handle session changes more gracefully. You can change this in the game's video settings.
3. 3 If you're using remote desktop, make sure your network is stable. Use a wired Ethernet connection instead of Wi-Fi if possible. Also, close any other bandwidth-heavy applications.
4. 4 Press Windows key + X and select 'Device Manager'. Expand 'Display adapters', right-click your GPU, and select 'Properties'. Go to the 'Driver' tab and click 'Roll Back Driver' if available. This reverts to a previous driver that might not have the bug.
5. 5 Press Windows key + R, type 'regedit', and press Enter. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX. Create a new DWORD (32-bit) value named 'DisableSessionDisconnect' and set it to 1. This tells DirectX to ignore session disconnections, which can prevent the crash. If the key exists, modify it to 1.
