Re: My sims 4 won't open
When a file is opened by a program it can not be deleted. Likewise the game can not be repaired when it is running.
Restart your computer and before starting the game 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.
