Problem in launching game in Steam

Hi! When I launch Civilization 6 the game won’t show up / start and in Steam it says that the game is running.
I’ve tried to uninstall steam, uninstall the game, delete the com.valvesoftware.Steam file, restarting my PC and using the kill command on terminal. Can’t start a steam game. Tried everything. I have 3.5.6 Endless os. When I wrote sudo flatpak updatwe saw this:user@endless:~$ sudo flatpak update

Looking for updates…
