I recently updated my laptops AMD Vega 8 drivers to 20.4.2 and my game started dropping from 100 FPS to 9 frequently. My laptop is a Lenovo IdeaPad S340, and all my other games such as Overwatch and Valorant run normal after this driver update. Please help!!

@annamu1 Please open the AMD Crimson control software (you should be able to access it by right-clicking on your desktop), open the profile for TS4_x64.exe, and disable every optimization or other supposedly helpful setting you can find. If you don't see a profile for TS4_x64, you can create one and then disable all the custom options. Let me know whether this helps.
If it doesn't, please run a dxdiag and attach it to a post.

@annamu1 The dxdiag doesn't contain any errors directly related to your GPU driver, which is a good thing, but it also makes it more complicated to guess what's going on. Since you do have a few Windows update failures, it's a good idea to start with a couple of basic checks on your Windows system files. Here's how:
Restart your computer, hit Windows key-i, select Update & Security, and click the button to check for updates. Run any you find, restart again, and test the game.
This may do nothing for your low fps though. If you still get low framerates, please try playing in a clean user data folder, for comparison. Move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content. Don't add anything to it yet; just start a new save and see what fps looks like. Please test in a few different worlds—you can just have a sim travel—including one or two that are not Evergreen Harbor or San Myshuno. Let me know what you see.
Your saves and other content will be intact in your old folder but not read by the game for the moment. You can add back the files later; for now though, it's best to see whether the fps issue has to do with the user data folder or something on your system.
