OK. We need to check if the problem is in Sketchup instead of VR Sketch. Could you please insert any public model from the 3D warehouse into your model (“Download”, “Load directly into your model”)? And then immediately afterwards, open the Ruby console (Extension -> Developer -> Ruby Console), and copy-paste this text at the bottom, all in one line:
Sketchup.active_model.active_entities.add_instance(Sketchup.active_model.definitions.load_from_url("https://3dwarehouse.sketchup.com/warehouse/v1.0/content/restricted/3d62546f-64b0-4d1c-87a6-8d516b38d01c"), Geom::Transformation.new)
This should insert a model that contains the cardboard woman and some off-center simple floor+wall plan of a house. Does this work for you?
