Guild Wars 2

I am updating my client, when finish, I will try play on open world, try some world bosses to see if it still crashes, maybe I take a screenshot of the error and reply here.

the same thing happens to me since I begun play the game, the game crashes a bunch of times when I stay on the open world, the game closes and appears a window titled gw2.exe error, ask to send the error but nothing happens.
I will try reinstalling the game but I’m not hopeless about it.
