EA Help posted that they’re currently working on a glitch where it takes a long time to bypass the loading time after starting The Sims 4.
We’re aware that some players are experiencing extended load times at the The Sims 4 logo or the plumbob screen when loading the game. Our team is currently investigating in order to find a solution.
In the meantime, putting Origin into Offline mode (click the Origin menu and select “Go Offline”) has allowed some of the affected players to be able to load The Sims 4 and access.
Stay tuned for more updates.
