Your error is not with the amber. As the error following PQR suggest,
the problems lies your parameters for molsurf. mm_pbsa does not
provide the fluorine radius parameter for molsurf so you will need to
hand edit the code yourself to enter the value.

I guess amber should read charge and radius parameters from prmtop file. But the pbsa failed with an error message as following:
