@Eshja Do you happen to have Windows set to compress Documents, or the Electronic Arts folder or the Sims 4 folder inside, to save space? You can right-click on any folder and select Properties, then under General, click Advanced and look for an entry that says "Compress contents to save disk space." If this is enabled, it could prevent the game from reading certain files correctly. Please check your C drive as well; the option should just be under Properties > General.
Additionally, your dxdiag lists a number of Windows update errors. So it's a good idea to run a couple of basic checks on your Windows system files, then manually run any updates.
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, 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 “Command prompt (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
- Post the message you receive here
- Restart your computer, hit Windows key-i, select Update & Security, and click the button to check for updates.
