Volume rendering does not work after reloading scene

Problem report for Slicer 4.11.20210226 win-amd64:

Hi there

I cropped a volume and saved everything into a scene. After reloading the scene, I can
only see the 3D rendering of the cropped volume. The rendered original volume does not appear, even though the volume is set to visible. Also I noted that the crop bar is deactivated in the Volume Rendering module for the original volume only (usually this is activated for other volumes). Slice views are normally visible though.

Any suggestions? Thanks.

Logs do not provide much, unfortunately:

This issue was fixed some time ago in the Slicer Preview Release.
