Issue with relogging/exiting game

I have been having this issue for a couple months now but it is becoming more and more frequent.

Basically, at random times when I try to exit the game/log out/go to character select, the game camera freezes in place, all animations are idle, and if I try to move, the character will move to wherever I clicked and be stuck. I now have to alt+f4 the game no matter what I was trying do.

I have no idea what's causing this and haven't really tested anything. Please let me know of any solutions. Thanks
