​There are ***s in your inpcrd file. Look at line 28587:

​ 115.5537065************ 12.6537715 115.0636064************ 12.6532888
 115.3578012************ 13.5033254-891.8520828 493.4722293 62.3942084

​This indicates that you have an overflow as some coordinates got too
large. If you are using Amber 14, the error message from sander or pmemd
should indicate what went wrong and how to fix it (i.e., use iwrap=1 in
your input file).

Both Dave Case and I suggested that you look for "*" characters in your
inpcrd file in previous emails, which is a common problem that has been
discussed many times on this list previously. To save us all time, please
be sure to read the answers you get on this list carefully and try all of
the suggestions in the future, or ask for clarification if the suggestions
are unclear.

All the best,
Jason
