QDS stops repsonding when closing project while inside component

To reproduce.

1. Create a new 3D project.
2. Import a 3D model and add it to the scene.
3. In Navigator, select the 3D model and press F2 (Go into component).
4. In the file menu, select File > Close project "Projectname".
5. In the breadcrumb , select Screen01.ui.qml. Now, QDS stops responding.

I tried this with QDS3.0 quickly and it worked fine there.
