Same issue for my wife laptop.
I am running on Windows 11, Dx12, Alienware and it did it once and never did it again. Weird.
My wife laptop, Win 10, Dell, freezes everything! Even Task Manager is frozen to death. Rebooting does not fix it. No add on. Killed razor and Nvidia background apps with no improvement. Running as Admin does not improve it. She is pissed at ArenaNet.
How could they stuff up something that was working properly...?
And we will have to WAIT A WEEK until the patching of the patch?!?
That is quite an urgent issue. I would expect a special patch within 24-48 hours (ASAP). A week is not ASAP; that's just the regular schedule.
I works for me too.
