Error when adding Quick3D Material to the navigator first time

Getting "Component could not be created" error when dragging and dropping one of the Quick3D Materials to the navigator. This seems to happen when adding a material first time, second try and the ones after it succeed.

Steps to reproduce:

• Create a new project
• Add QtQuick3D.Materials import (in snapshot import seems to be QtQuick3D.Materials 1.14, should this be 1.15?)
• Drag and drop one of the materials to the navigator -> error as in attached picture appears
• Drag and drop other materials -> no errors there
