From the moment I load up ME LE on my PC, the Xbox one controller doesn't work. So I was just going to forgo that cause i wanted to play but from the moment I load it up, the camera behind Shepard keeps rotating. It is almost as if someone is holding the joystick to the upper left so it just looks down and spins over and over and over. I don't know how to stop it. I've disconnected the controller and rebooted, uninstalled and reinstalled, tried different options in the settings but nothing. it's impossible to play the game like this. Here is a Reddit post from someone having the exact same issue:
