Re: Sims 4 will not close
@Leelosingmarbles First of all, instead of shutting down your laptop, you can hit crtl-alt-delete and choose "sign out" instead of trying to open the Task Manager. This will throw you back to the login screen and also close any running programs, including Sims 4.
For the game issue itself, does Sims 4 ever freeze other than when you're trying to close it? Does it only freeze when you use "save and exit," or also when you try to exit without saving? Please run a dxdiag and attach it to a post as well.
