Hello Slicer team!

**OS** : Windows 10 (22H2)  
**Slicer Version:** 5.6.2  
**RAM** : 128 GB

**Data** : DICOMs (12.4 GB)

**Expected Behavior** : When using an ROI to define a cropping region (both in the Crop Volumes module and when using the ROI in the Volume Renderer), I select the active volume as my Input Volume, successfully resize the Input ROI, create & name a new Output Volume, and click “Apply”. The new Output Volume contains only the region of the Input Volume within the Input ROI.

**Actual Behavior:** The cropping does not occur – the new output volume remains empty. When attempting to view the cropped Output Volume, I hide the original Input Volume, show the Output Volume, and the cross-sectional views display only the middle slice of the original Input Volume. When I attempt to scroll through the slices in the new Output Volume, the scroll bar snaps to the far-left, center, and far-right (3 “slices”), but the images themselves do not change.

This issue persists for different Input Volume formats, including .nrrd files.

Does it work well for smaller volumes? For example volumes in Sample Data module.
