My sims 4 keeps crashing on the loading screen

@AngryFemiKeagan  Please run chkdsk:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste "chkdsk /f /r c:" without quotes, and enter
• You'll be asked to allow a restart; say yes
• When the scan is done, use this guide to find the results, and post them here

@puzzlezaddict thank you!!! it hasn’t worked for months tried everything and this worked. lost all my saves but it was worth it

@whitehamm  You should be able to move your saves to the new Sims 4 folder the game has created.  The saves themselves might be corrupt, or not; the only way to find out is to test them.

Since this thread is a bit old, I'll lock it here.  But please do create a new thread if you'd like further help with this issue or another one.
