Game is unplayable because of constant freezing

My game has been unplayable for a month now. I have two instances where it looked like the game was back to running as normal, but then the problem occurs again and I'm back to where I started.

The game loads up as normal, everything appears to be running fine, but as soon as I click anything it instantly freezes. This happens in every mode and every save file. It will run for about 10 seconds, then freeze, then repeat the process over and over again until it eventually completely crashes, or I have to manually ctrl-alt-dlt to exit the game. 

I recently completely reset my computer to factory settings. I've uninstalled and reinstalled the game several times. I've repaired the game. I've tried playing with a clean save file. I've cleared the cache.  

This is a new, gaming computer. I have no other games installed except for the sims 4. There is plenty of space on both of my drives. My graphics card is up to date. 

I've tried playing offline. 

I have no mods or cc and haven't had any since any of these issues began.
