I've posted a bit about how the game will sometimes not respond on exit and you have to force quit while also mentioning the game freezing, but wanted to put a post to be more on that.

So not only is the game freezing when I try to tab in and out of the game, or go from one window to the window of the game if playing on windowed mode, but the game is also freezing if I even go so far as to try to copy something. It could be going to copy something on the party finder, or shading a text box and then try to copy it. Freezes either way. I am on a late 2019 iMac and none of these problems were happening before the 6.4 patch.

Also the game not quitting completely when I exit is also happening. Mostly gives me a black box on the corner of my screen that makes me have to force quit to remove.
