I was composing a technical drawing in Layouts. While editing a title block, the BlockEdit window closed by itself and ALL objects became grey and completely locked. Now the BlockEdit is unable to select and therefore edit any blocks.
There are two blocks in the scene, my selfmade title block, and a McNeel example title block. The McNeel block is on it’s own layers, and my title block is on a layer containing scene objects. Neither of the block definitions can be deleted because of the reference objects.
(I was able to save the project through STEP import)
