When I exit the game, the Steam page remains on Stop even for hours. The same happens if I click stop and Shutdown appears, it never completes successfully.
Sometimes I have a similar problem. After exiting the game and saving, it takes forever for anything to happen. Steam still shows inZoi as “open and in-game.” To get around this, when I want to close inZoi, I just select “Save,” return to the lobby, and then exit the game.
