After my PlayOnLinux setup stopped working a long time ago after some Origin update (and several retries afterwards), we tried running the Steam version of the game using Steam's Proton environment and we could start the game only once and then it stopped working again. If you check protondb there seems to have been a regression two weeks ago.
The frustrating part is the game itself would be working like charm in Wine but the stupid launcher app keeps getting updated and is doing all kinds of complicated DLL and system calls although all it really needs to do with respect to "Sims 4" is to check your license and start the game.
So even if you get the game running for some time, ultimately, "Origin" will stop working one time or another.
