Have you checked to make sure you've tried playing the game first, so it will make a new Sims 4 folder?
How to do this - Log into Origin with your username and password you used to purchase or register the game with, go to your Games Library and click on Sims 4 to play. Exit the game, and go to: C:\Users\Username\Documents\Electronic Arts\The Sims 4 to see if you now have your Electronic Arts folder.
If not, you may need to search your computer by clicking the Start button and search for Sims 4.
If you have OneDrive installed and activated, you may want to un-sync it, as it and the Sims games don't work well together and will mess things up.
Turn off, disable, or uninstall OneDrive
