Hi Queen.jay,
Good day! This is Jhakesong an Independent Advisor and I will be happy to assist you with this.
This could be an issue with the Visual C++ redistributable file that is required by Sims4. You can try to download the latest one here:

Download the x86: vc_redist.x86.exe x64: vc_redist.x64.exe that is under the Visual Studio 2015, 2017 and 2019 title header.
Restart your computer after install and try Sims 4 again.
Let me know how it goes. Have a great day!
