@epaorGo to the Documents/ Electronic Arts - inside this find The Sims 4 folder
Look for localthumbcache.package file and Events file - this one looks like a cogwheel. Delete both files. Don't worry the game will recreate it but with the correct version.
Next, go to the Origin/Library - right click on TS4 - option "repair game"
Warning
If you have any mods then the first step is moving mods folder to the desktop.
I don't work for EA.
