Re: Sims 4 will not launch on EA app
@Mack232323 This means that the problem is within your main user account, but there could still be a few different sources. First, go back to your main account, and if OneDrive is running on your computer at all, whether you use it or not, please pause syncing. You can see the option by right-clicking the cloud icon in the lower-right corner of the screen. Then try to play.
If that doesn't help, move the Electronic Arts folder out of Documents and onto your desktop, still with syncing paused. (This is in addition to having moved the Sims 4 folder—the permissions could be borked on the EA folder.) If the folder copies instead of moving, or you get an error when trying to move it, stop here and let me know. Otherwise, test the game again.
If that doesn't help either, let me know whether a new Electronic Arts folder was created with a Sims 4 folder inside. I suspect the answer will be no, but it's worth checking.
