Re: How do I fix my Sims 4 broken UI?
@madabanana When you moved the entire Sims 4 folder, did it look like you were playing in a clean folder, or did you see your saves and mods? Like I mentioned before, it's possible that OneDrive redownloaded your content, in which case the mods would be present as well as everything else.
If you're sure the user folder is completely clean—no mods, no cc, nothing at all—try repairing: open your Origin game library, right-click on the Sims 4 icon, and select Repair. If that doesn't help, try changing the in-game resolution and switching between fullscreen and windowed mode a couple times.
