In this case, potential energy decreases but velocity of the body increases due to gravitational acceleration. Hence the kinetic energy of the body increases, which makes up for the loss of the potential energy. Thus, it may be said the total energy of the system remains constant. Therefore, law of conservation of mass is not violated in this case.

law of conservation of mass:
energy can neither be created nor be destroyed, but can be converter from one form to another.
no, potential energy is converted to kinetic energy.
