Re: How do I fix my sims 4 thats telling me to relaunch my game?
So you have determined that the cause is broken mods.
Move your Mods folder to the Desktop and delete localthumbcache.package. Then test the game in a new save.
If it works now check for updates to your Mods and CC. Add it back a little at a time while testing until you have found all that are broken.
