Same thing happening to me… Launcher doesn’t open, only an icon appears in dock.
It was happening to me a month or two ago and I solved it with the help of GW2 support team. So I suggest you send a support ticket
I really really really want those white wings and now I probably won’t be able to get them…
And also while I was still able to launch GW2 and play it today it has crashed 2 times.
