Game Isn't Keeping My Mouse Inside of the Screen

On the boundaries between monitors, if I move my mouse too far it goes outside of the game. I cannot move my camera around to see.. How do I fix this?

I've tried Windowed, Full Screen, and Borderless Windowed, and none of them fix the issue. Full screen is notably the worst as it completely minimizes the game everytime I click outside of the screen. I've never had this problem in the past, and nothing has changed on my computer (of which I'm aware). Not certain what exactly the problem could be, but this is a fairly major issue which prevents me from even being able to play.
