@PrinceNeopolitan This error is currently mostly due to antivirus software blocking Sims 4 from starting. The game's default executable is now TS4_DX9_x64.exe, for the DirectX 9 version; only DX11 uses TS4_x64.exe. So set an exception for TS4_DX9_x64 if you haven't already.
For some antivirus programs, and perhaps Windows Defender too, it may be necessary to set an exception for the entire folder.
