Lycarii The Sims 4 folder (inside the Electronic Arts folder) that contains your user data is only created when the game loads for the first time. So if it's not opening, it's no surprise that you don't see the folder.
When you restored your PC to factory settings, did you import any of your old data? It doesn't sound like you did, but let me know if you're reusing anything.
Otherwise, please create a new admin Windows account and try playing there. Make it local, as in, don't link it to your Microsoft account or any email address. You'll be able to (try to) launch Sims 4 without reinstalling anything. The idea here is to see whether the problem is limited to your main account or not.
If the game won't open in the new account either, please provide a dxdiag. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
If the game does work in the new account, but you want to play in your old account, please list the location of the Documents directory in that old account. Search in Windows for Command Prompt, open it, and enter this command:
reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders" /v "Personal"
Then post the result.
