Unresponsive PS4 controller

[Tempest222]

Not sure if this is the correct place to post this, so apologies.

I play the game on PC with mouse and keyboard normally, but today I decided to plug in a ps4 controller to see how it would feel playing that way. I switched the input to gamepad and clicked out of the settings... and apparently this was a terrible mistake because for some reason every button on the controller seems to work, except for the Dpad buttons. They worked for a few minutes, and then became completely unresponsive, and now I seem to be stuck in gamepad mode with no way of switching back to mouse and keyboard because it seems I need to dpad to be able to navigate to the settings.

So now I can't even play the game on my main which is an issue... So is there something obvious I'm overlooking that will get me out of this predicament short of purchasing an xbox controller?.. Or I guess reinstalling the game would put me back to mouse and keyboard control?

Ok.. haha never actually looked at all the things on the menu when you hit escape. Can get into the settings from there. Facepalm.
