[BUG] Left Click not moving or attacking in-game, won't allow me to set hotkey to MB1

I'm a player on NA and today I got in game and my left mouse click wasn't working to move or auto attack. It opens up shop and can click on the menus just fine, but just doesn't work to move or auto attack like normal. I tried repairing files and restarting the client but neither worked. Thanks for the help!
