Don't you know why the animation of my character will be cut after I turn the camera view to the left from the side?

first of all, I apologize for my English. I’m not from an English speaking country.

My problem is that when I turn the camera view to the left, the character animation gets stuck after a while. After rotating the camera view in another direction, the animation is corrected again. Don’t know what could be causing it or where to look for a repair? For more info, don’t hesitate to ask, I have no idea where to look for a fix.
