I had the exact same problem, I even contacted Playstation Customer Service with no help. I think it's the game not having the correct update for playstation. I got mine for Christmas also. I had a grand theft auto game on playstation 4 that played perfectly fine its just the sims 4 that crashes every 5/10 minutes during gameplay during different activities. I returned my PS4 and got an xbox one s and now I'm able to play the sims 4 perfectly fine during game play. It just sucks I had to change my console to play the game. I heard from a worker at gamestop that ea is working on an update and that there is a problem with the sims on playstation 4. He said they an update every month. Unfortunately everyone just has to be patient. I couldn't be patient so I just switched systems since mine was brand new. Reminds me of how Apple will have a bad update they would release then have to work on a new update with bug fixes.
