If you DON'T play on official, you could try to launch without battleye: go in "Library", then on the list of your games, on the left of the screen, you see Ark, you click on "play", then, a NEW menu appears, you choose the 2nd one from the top (excuse me if all is not perfect in English, i'm French! ) , and it could work, i just tested for you and i'm on i'm on P+, this way...
