A newer version of VTK may be causing segmentation fault on some occasions.

Please see [pcl::io::loadPCDFile() causes segmentation fault on ubuntu:26.04 · Issue #6388 · PointCloudLibrary/pcl · GitHub](https://github.com/PointCloudLibrary/pcl/issues/6388#issuecomment-3714163357) .

Apparently this was because of a dependency issue in the PCL apt package, and now it had been fixed [pcl::io::loadPCDFile() causes segmentation fault on ubuntu:26.04 · Issue #6388 · PointCloudLibrary/pcl · GitHub](https://github.com/PointCloudLibrary/pcl/issues/6388#issuecomment-3822892655).
