What is the bug or the crash?

HI,
I'm working with point clouds.
After importing one copc.laz file, it is shown well in 2D and 3D with RGB styling (as set below)
Contrast enhancement is set to stretch to min/max

But when I set contrast enhancement to 'no enhancement' then point cloud disappear from 2D and 3D canvas

Steps to reproduce the issue

Go to Styling properties
Set Contrast enhancement to 'no enhancement'
Then, point cloud disappear from 2D and 3D canvas
