Update: Full Copy doesn't crash if the scene is completely empty, i.e. not containing any objects, camera or lights (or anything else).

I can confirm here. Looks outliner related:

base variable is nullptr

Funny, yes. If I get rid of the Outliner I can actually do a "Full Copy" without instantly crashing Blender,. But as soon as I change the layout containing a Outliner again it crashes.

@SteffenD Thanks for providing the has of a recent version that did still work. Made it lots easier to find out that ac723db57f caused the issue.

The crash occurs in outliner_add_layer_collection_objects(), because BKE_view_layer_base_find(layer, cob->ob); returns NULL (i.e. it cannot find the object's base).
