Game Freezes on exit since last patch

[Badwolf.9725]

As title suggests, since the last patch, when I exit the game, it will instead freeze until I logout/shut off my computer. No Alt+F4 working, task manager doesn't list the game at all, etc. It just will not fully close.

 

Additionally, after each failure to exit, when I first load up the GW2 client, a pop-up appears and says the game need to verify the game's files and it doesn't seem to fix the game at all.

 

Thanks
