Problem report for Slicer 5.7.0-2024-12-13 win-amd64: [please describe expected and actual behavior]

Dear community,  
I’ve done tractography in the 3D Slicer 5.7.0 software and now I planned to export my fiber bundle as a ply in order to continue processing and make a 3D print. With the 5.6.2 software I had no problem and the export went well. Then my 5.6.2 software crashed sometimes during my work and I decided to go for the newer version. Now my question: Is it a generell bug, that the export modul doesn’t work in the 5.7.0 version or maybe, did I do something wrong?  
Any help and advise is much welcome!  
Best regards, Elisabeth

Are you using this script?

[https://slicer.readthedocs.io/en/latest/developer\_guide/script\_repository.html#export-a-tract-fiberbundle-to-blender-including-color](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#export-a-tract-fiberbundle-to-blender-including-color)

As far as I know any recent version should work.

If you are getting a crash, please report the exact steps how to reproduce, ideally using public data (there are DTI scans in the SampleData).
