[PC][Steam]All the sudden my arrow keys control the camera and it's making the game unplayable :(

I’ve had BL3 on Steam since release day. I use the arrow/cursor keys for movement since I am left handed. I had a crash today, and rebooted my PC. When I loaded back into the game, all the sudden, the arrow up and down are also rotating the camera up and down in addition to moving me forwards and backwards. If I move forward, I end up facing the ground. If I move backwards, I face the sky. This basically makes movement impossible. I reset all my keybinds, rebooted, etc, but nothing is reverting this and it’s driving me mad. Is there a hidden setting somewhere to prevent any keys from moving the camera?

Doesn’t arrow keys on PC triggers emote?
