You have bad coordinates on input. The first step is to use the "check"
command in cpptraj to look for bad bonds and close contacts.

But a second step is the double-check all your file names. You seem to
be doing a restart, so it is somewhat unusual to see a failure on step
0. Do a single step of minimization, and compare the energies to what
you had on the final step of the previous run. That might help find
some errors.

Finally, you could look at atoms 1785 and 1787: is the geometry around
that area good?
