I am going to restart my pc, check for updates and then post a new dxdiag soon 

Hello, my file isnt located in one drive it is here: C:\Users\PC\Desktop

I have just Repaired the game through steam as you instructed and it now says Update Failed then underneath it says Disk write error and when i click resume update it instantly stops and the resume button reappears 

I am trying to follow the steps of the checks you have suggested and when i click windows+x neither PowerShell(administrator) or windows terminal(administrator) appear the list of options i have are below:

Apps and Features, Power options, Event Viewer, System, Device Manager, Network connections, Disk Management, Computer Management, Command Prompt, Command prompt (admin). Task manager, Settings, file explorer, search, Run, Shutdown or sign off, Desktop.

Also yesterday i uninstalled and reinstalled the sims 4, played for a while and it worked completely fine until now where the issue has occurred again 

Sorry im not really an expert with game files and things like that, thanks 

kylef06  Please let me know whether your new Sims 4 user folder is in OneDrive.  Right-click the folder and select Properties > General, then look for the Location.

When you play through Steam, you need to repair the game through Steam.  The option is called "Verify integrity of the game files" and is under Properties > Installed files.

Your dxdiag crashed twice while running, which could be a fluke or a sign of a system issue.  So please run a couple of basic checks of your Windows system files:

• 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.

Then run and provide a new dxdiag.
