@PoptartJuniperIt seems to have been an issue for many people for quite some time but it's not happening only on the Sims 4, so I'm not sure what is causing this. As stated above, it appears okay once I disabled "sims delivery". Quick note about sims delivery: when it says on the menu that there is new content to be downloaded, I click to accept it then click the restart prompt, and this 100% of the time causes this error (took too long, etc) and I have to reboot again, sometimes a few times, which led me to believe this was a game issue. Although I was getting this error before sims delivery came to be, it's happening more often with it there. I'm not an expert but it might have something to do with the online feature as you mentioned. I have good connectivity but this could be the issue since sims delivery requires online access. We have internet though the main building complex ( not our own router) so even though it's fast and reliable, it may be the issue.
