Uh oh, I think something may be broken internally on my 50 1.4

I was just getting ready to go shoot a show, and while waiting for some friends to arrive, I decided to play around with the camera by taking a picture of my cat. Went into live view and noticed that I was getting a red square, even though I wasn't too close and there was plenty of light so it could focus. Switched out of live view, and still, no focusing. Turned autofocus off and tried focusing manually, the lens would not budge. The focus ring moves fine, but the lens is locked on 0.45m.

I don't remember dropping it or bumping it or anything.
