sims not opening

being on mac, i used to have origin. since switching to EA, ive downloaded the EA app. i recently bought some packs but noticed they would not show up when opening gameplay. when opening it, id recieve an error code that i thought could be related, and when looking into that, it told me to delete origin since i cant have both on my laptop. after lots of trying to figure it out, i deleted origin. now my game wont open at all. the application bounces in the dock appearing like it'll open, but then the EA app just opens back up and no sims. ive talked to 3 EA support workers on live chat, tried everything they told me as well as some methods on this forum and still nothing. please help.
