Game crashes every time I try to launch it

ph00roo  Sorry for the late reply; I didn't have time to deal with this forum for a couple days.

Please disconnect all nonessential devices from your computer, basically everything except for the keyboard and mouse, even your speakers.  Restart your computer and try again to play.

If that doesn't help, please clear the EA App's cache:

https://help.ea.com/en-us/help/faq/clear-cache-to-fix-problems-with-your-games/

and repair the game (EA App > Sims 4 > Manage > Repair, or Steam > Sims 4 > Properties > Installed Files > Verify integrity of the game files).  Please do this even if you have before.  Then try to play again, still with your old Sims 4 user folder moved to the desktop.
