Hi,
Try pressing Ctrl + Esc or the Windows key to see if the taskbar reappears; if not, right-click the desktop and open Display settings, then go to Multiple displays and select Detect to refresh the screen layout. You can also open Task Manager (Ctrl + Shift + Esc), find Windows Explorer, and click Restart to reload the taskbar without restarting your PC. If it only happens after using Steam, disable the Steam Overlay in Settings, In-Game to check if that prevents it. These steps help determine whether the issue is with Windows Explorer, Steam’s overlay, or a temporary display glitch.
Kind regards,
