EA app will only open in Epic Games Launcher ... I don't have that!

TS4 won't open the game unless it is in the Epic Games launcher, which I don't have installed and never have had installed on this laptop. It's frustrating because after the pop-up my game won't open, and theres a 5% chance the actual Sims 4 will open. I have tried removing mods, custom content, save lifes, reinstalling the game, restarting the EA app... everything! I'm going insane! This has been going on since New Years Eve.
