Re: Sims 4 starts up in small unresponsive window in the bottom left corner
@hbox36012 The first thing to try is to turn off Origin in-game: Hover over your username in Origin and select Application Settings to see the tab.
If you still can't launch the game, drag your entire TS4 game folder out of Documents and onto your desktop. When (if) it launches, a clean folder will spawn with no content. If you can start a new save in this folder—no need to spend time on it; this is just for testing—you can move the contents of your Saves and Tray folders from the old game folder to the new one.
