If you’re running mods in your game, you should always launch and test The Sims 4 with mods disabled after an update. There are a few tell-tale signs if mods are creating problems in your game. The process can be tedious, but the best way is using Sims 4 Studio (a free tool for making custom content) and Sims 4 Tray Importer.
If your mods are not functioning properly in S ims 4, there are some free tools created by the modding community that will help you find and delete the files.
