Sims 4 launches but stops responding at the main menu

@stab_crab  Your dxdiag crashed multiple times when running and is missing most of the critical information, which points to a system issue.  It might not be a big deal, but it's difficult to say without a complete dxdiag.  Please start by running a couple of basic checks on your Windows system files:

• 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 and run another dxdiag; hopefully this one will have all the relevant info.
