If you were originally launching from Steam, you bought it from Steam. Plus, you are saying you also bought from Epic? It's no wonder you are having problems launching.
I suggest you contact EA support directly to see if they can untangle this.
I just want to make sure you are on the right track here. I can easily launch the game just like that. I press play on EA. and then it launches from Epic. It loads up the game, I'll either try going to a multiplayer match selection or instant action. It brings me to a loading screen before the game freezes and I see a small glimpse of UI, but the UI's just like some white outlines. And then the game Crashes. Also. I can play the campaign. But as soon as Iden leaves the initial starting ship, the game crashes and I can't continue on at that point.
