How do you fix a game that is stuck running on steam?

To fix a game that is stuck running on Steam, first try closing the game through the Task Manager by right-clicking on the taskbar and selecting "Task Manager," then ending the game's process. If that doesn't work, restart your computer to clear any lingering processes. You can also verify the game's files through Steam by right-clicking the game in your library, selecting "Properties," then "Local Files," and clicking "Verify Integrity of Game Files." If issues persist, consider reinstalling the game or checking for updates.
