Why did lighting get like this all of a sudden and how to fix it?

looks like you are using MatCap shading, and maybe you ratated the lights using 3 fingers, you can revert it back to normal in the shading panel (sun icon) and at the bottom put Rotation to 0. Hope it helps!

Thanks a lot that worked. I dont know how but I messed the rotation somehow, after returning the rotation to 0, it went back to normal

It happens more than you think, you are rotating the model, then rescaling with two fingers and then… swap! a third joins the party and lights go bananas.
