Cant play games cause of dam Epic Games Launcher///

Dear visitors of the forum. I have a rather unpleasant situation with launching the game. A long time ago I got this game from Epic Games Store and played on the first account. And now, I downloaded the game via EA app to play and remember those not so long ago, but I can't, because Epic Games Launcher opens with my new account (where there is no Star Wars Battlefront2) and there is an endless download. Is there any way to unlink the game itself from Epic Games Luancher and without opening it. Thank you in advance for your help.
