If you make your archive available, I will take a look for the error.

In Mechanical, right click on Mesh and Clear Generated Data.

In Workbench, File, Save, then use File, Archive to save a .wbpz file.

Upload that file to a file sharing site such as Google Drive. OneDrive or Jumpshare.

Reply with a link to that file.  Note: if using Google Drive, make sure anyone with the link can download the file.
