When I click on the Sims 4 icon, my mouse does the loading icon and it attempts to load Origin but fails. When I load Origin itself and click play the Sims 4, nothing happens, just a quick loading icon on my mouse. I have tried everything including uninstalling both Origin and the Sims and reinstalling. Same problem exists. When I try and load it from my Nvidea GE force experience, it says I need a product code. Please help! I spent too much on extra packs to be not able to play!

@Arielle1084 The GeForce Experience issue is separate and can be ignored. When testing from now on, please always launch Sims 4 from your Origin game library, not from GFE or from its shortcut.
Please move your entire Sims 4 user data folder out of Documents\Electronic Arts and onto your desktop. When you launch the game, if it launches, a clean folder will spawn with no content. Don't add anything to this folder yet; just see whether you can play a new save for a bit. Let me know either way.
If that doesn't help, please disable Origin in-game: hover over your username, select Application Settings, then the Origin in-game header, and disable the option at the top.
If that doesn't help either, please run a dxdiag and attach it to a post.

After probably close to 10 hours of trouble shooting, trying everything I possibly could, I decided to delete my backup saves, tray and mods folder. Even though I told tech support several times the folder was on the desktop, nowhere near the reinstalled new Sims 4 folder. They didn't ask me to delete it. I put it on a USB drive and deleted it completely. The game worked. I popped my saves and tray folder back in and there was my saved game. I slowly started adding back the mods and found out that one of them had caused this whole issue. Even from the desktop folder. So it was the mods all along.
