@EsuMiwa7 Are you still testing with a clean Sims 4 user folder in place? (As in, keep your existing folder out of Documents\Electronic Arts and let the game generate a new one when you launch it.) If not, please do so going forward, at least until the game is working again.
Try playing while your computer is completely offline. You can sign into Origin and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before launching the game.
If that doesn't help, please look for any related errors in the Reliability Monitor. Hit Windows key-R and enter "perfmon /rel" without quotes. You'll see a list of errors and updates, with a column for each day. (Today is all the way on the right.)
For any errors that happen when you most recently tried to launch the game, click "View technical details," then copy the information and paste it into a reply here. Sometimes the Reliability Monitor doesn't update right away, so if you don't see any related errors, be sure to check back an hour or two. The timestamp on the initial chart can also be off by up to an hour, so that's not an entirely reliable metric, but the one within the technical details should be accurate.
