@sotarad I’ll investigate at the issue once you are able to send the dataset.

You could also try the workaround in this post: [Retrieving statistics from RTSTRUCT and scalar volume - binary labelmap representation computation is very slow - #5 by Sunderlandkyl](https://discourse.slicer.org/t/retrieving-statistics-from-rtstruct-and-scalar-volume-binary-labelmap-representation-computation-is-very-slow/28100/5).
