AttributeError: 'CtrlLayer' object has no attribute '_ndisplay'

[QuentinRapilly]

Hi,

I want to use napari-splinedist but when I run it on an image, the process doesn't work.
The following exception is returned :
_AttributeError: 'CtrlLayer' object has no attribute 'ndisplay'
It seems that it comes from napari-splineit which is used by splinedist to plot the results and in fact when I try to add a new empty layer using splineit I got the same error.

Full error is :
