I see you are using a very old version 16.0 which is not supported officially by us. Is it possible to try a newer version?
Also, it looks like some data is corrupted in the project as per the message. Have you tried running a simple project?
An unexpected error ( SIG$ILL ) has occurred...  ANSYS internal data  Â
 has been corrupted.  ANSYS is unable to recover and will terminate.   Â
 Previously saved files are unaffected.  Please send the data leading  Â
 to this operation to your technical support provider, as this will   Â
 allow ANSYS, Inc to improve the program.        Â

You can try renaming the %appdata%\Ansys folder to %appdata%\Ansys.old and then retry again.  Â
