ARTv1 Can't save Maya file after importing mocap

Whenever I try to save a Maya scene after I use the import FBX animation/mocap data feature Maya no longer lets me save. This is the error I get on Maya 2020 Student(version on school computers):

The import of the FBX works, the character animates after importing the fbx, I just can’t save the file.

The files are hooked up to source control using SVN. We’ve been able to save and upload scenes so far on it with no problem.

I downloaded Artv1 from the marketplace using the 4.21 version of the engine since it was the most recent version I could get it from the marketplace.

I’ve tried the following:

  • Saving an empty Maya file, works with
    no error.
  • Saving an Artv1 scene with a
    character and no animation, no error.
  • Saving an Artv1 scene with a simple
    hand keyed animation, no error.
  • Saving an Artv1 scene with imported
    mocap fbx, error, can’t save, but
    animation works.
  • Saving an Artv1 scene with a
    character and no animation, no error,
    then importing mocap fbx and saving,
    error
  • Importing mocap, exporting it as fbx
    using Artv1 export motion tool.
    Importing it again in new scene. Same
    error.
  • I’ve tried doing this on another
    computer using the same project files
    and source control account, same
    error occurs.
  • Resetting Maya preferences, same
    error.

Running the python code recommended for student version in the FAQ. I get this error

Error: line 1: NameError: file line 1: name ‘newName’ is not defined

Downloading the newest files from the FAQ dropbox and installing them did not fix it either.

What can I do?
