@pphhiiiaaa A dxdiag is a sort of system report: device drivers, errors, some hardware info. It's not totally comprehensive, but a more thorough report like an msinfo would also include personal or potentially compromising information. So a dxdiag is an excellent place to start when troubleshooting.
Do you use Reshade, GShade, or any other utility that changes how Sims 4 looks? If so, please remove it, at least for now, and repair the game (again).
Either way, please also run a couple of basic checks on your Windows system files—your dxdiag shows a number of generic Windows errors.
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
- The system will start validating soon. If it throws an error, please list it here
- After it reaches 100%, hit Windows key-X again
- Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes, and enter
- Post the message you receive here
Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates. If any install, restart again afterwards.
Reading your thread, I'm also unclear as to whether refreshing the Sims 4 folder tempoarily helped this time around, as in, did the problem disappear briefly before returing, or was it always present? Additionally, just to be clear, does this only happen in apartments in San Myshuno, or does it happen elsewhere in the world, or in other worlds? Please test if you haven't already; you don't need to save your progress.
