Empty render scene in jupyter notebook

[P-Light]

Describe the bug
In notebook:

data = PyntCloud.from_file(ply_path)
raw_cloud = data.plot(return_scene = True, backend="pythreejs")

It returns render scene filled with selected color (black is default).

Jupyter logs:

[W 16:07:57.148 NotebookApp] 404 GET /static/notebook/js/main.min.js.map (93.92.200.162) 2.42ms referer=None

In browser console:

Error: request failed with status 404
URL: http://server:port/static/notebook/js/main.min.js?v=68936091b7b2dafbb368b29294028b02

With backend="threejs" same problem, but no render scene is shown.

Expected behavior
Render scene with colored point cloud.

I also have the same problem. It was working well until I set up another environment.
