PLY Export failed


I’m trying to export pointcloud as PLY but keep getting a message saying the writing plugin failed.
Not sure what to dom tried looking for solutions here but nothing I found seems to apply or work.

Thank you

Hi Nadine -
That seems to work fine here with a quick test.
Could you post or upload the 3dm file?
Also, please run the Rhino SystemInfo command and copy-paste the result here.
