Hello,
Your VDW terms are too high, implying some type of steric clash. Study the
output files (_MMPBSA_complex_gb.mdout, or something of the like) and
visualize the generated trajectories with your prmtops to see if you can
locate where this clash is taking place. This may give you some hint as to
how to fix it.
Good luck!
