Re: steam not launching sims

@squishyermine94  No, there's no way to play Sims 4 without the EA App running.  If you have a third-party antivirus installed, please set exceptions for EADesktop.exe and TS4_x64.exe; do the same if you only use Windows Defender and Controlled Folder Access is active.  Either way, repair the game in Steam (Properties > Local files > Verify integrity of the game files) before trying to play.

If that doesn't help, please run a dxdiag and attach it to a post.
