The crashs on BKE_object_add due BKE_view_layer_base_find returning a null.

Still have to read up on usecases for overriding collections specifically, can confirm the crash though (and what @dgsantana said).

Note that if the sequence of linking-collection/creating-override/adding-object is done in a row, without going through saving/reloading a blender file (OverrideTestD), then the issue does not show up (see #71106 repro steps).

The crash should be fixed now (was same issue as #70875, fixed by 74af698769.

Keeping that one open though, as it should not be possible to add objects to an overridden collection (that is not supported currently, although it might be in the future).
