   Are you running calculations locally or on an HPC resource? I have
encountered segmentation faults in the past when the instruction logs for
CPUs have been updated or changed. From the output file, it looks like the
executable 'sander.MPI' is not being recognized. Are you able to run any
other AMBER18 executables in your current environment?
