@107531kop As a test, please save your sim to your in-game library and place them in a new save. If you see the same issue, try playing a new save in a clean user folder. Move the entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, launch the game to create a new folder, and just run a new save for a few minutes to make sure the game is working properly. Then you can transfer the Tray files from your saved sim—they'll all have the same timestamp, matching when you saved the sim to the library—to the new Sims 4 folder, and you'll be able to place your sim in a new save in that folder as well.
I'm not suggesting you necessarily need to abandon this save, just that this can help narrow things down. And I understand that this happened after an update, but it can't be only about the update itself or we'd be seeing a lot more posts describing the same issue.
