We cannot guarantee there won't be problems. There's a lot of factors that come into play.
If you haven't updated to the current game patch - PC 1.46.18.1020, you might try backing up the Sims 4 folder to your desktop or a USB drive for safe keeping, then try updating.
When I do updates, I backup my Sims 4 folder, delete the current one. Launch the game to create a new Sims 4 folder and then copy over these files and folders, checking all mods and custom content to make sure they're up to date with the current patch. As outdated mods/cc can cause a lot of issues.
- Options.ini (User game settings)
- Tray Folder (Sims/Houses/Commercial lots and rooms)
- Screenshots/Videos/Custom music
- Saves Folder
(leave out slot_00000001.save which is the autosave. It is not used anymore.)
- Custom content like clothing, hair, skins, and makeup
- Mods (Put these back one by one to make sure they all still work)
