@mariana102004 Please move the entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop. When you launch the game, a clean folder will spawn with no content. (Your saves and other content will be in the folder you've moved but temporarily not read by the game.) Don't add anything to the new folder yet; just see whether things look normal in a new save.
If not, please change the in-game resolution a couple times.
If that doesn't help either, please post a couple of screenshots showing the issue.
@MOpoku11 Test your mods and figure out which one or ones are causing the problem. If you have a lot of mods and custom content, the 50/50 method can make the process more efficient:
