Sorry, that was only one of the problems.  As you can see from the log, 
when you open your file in ChimeraX, there are many bad PDB records.  
See 
https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/framepdbintro.html 
for details about the format, or the full PDB format documentation at 
https://www.wwpdb.org/documentation/file-format.  There are also lots of 
duplicate atom serial numbers that confuse things.
