Tested with 128Go of ram. Crashes after waiting a 'long time'. So probably when initiate the display

What is the size of the dataset?
Do you select the 3D view manually or is it opened automatically when opening the dataset?
Is it only with the 3D view? or with other as well?

The volume is 2048x2048x2048.

Other display mode (image stack...) works well.

The error arrives after a couple of minutes once clicked on the 'cube' view.

After discussion with @t20100 this clearly comes from the size of the volume. A warning could be add.
