The 3d editor window uses 3d features of the graphic card. If it is not available the most common problem is that etcher no 3d graphic card is available or the required driver for that card is missing.
Try to run any example/application using the qt 3d feature. If it is running the 3d window of the LayoutEditor will run as well.
