Short description of error
Right clicking on a collection of a linked scene (from another blend file) and selecting instance to scene instantly crashes Blender.
On a related not,

Exact steps for others to reproduce the error
I've made a very basic example, with two blend files, one linked into the other.

  • Open Blend file "...Base.blend"
  • In the scene selection dropdown at the top, select "Linked Scene"
  • Right click on the one Collection in the outliner and select Instance to Scene
  • --> Crash.

On a related note, how do I select which scene I want to instance my collection in? The instance to scene command doesn't give me a way to select any other scene in the blend file. ? For sharing assets between scenes.

Thanks for the report! I can confirm this, and it also leads to a failed assert in a debug build:

/* Only case where this pointer can be NULL is when scene itself is linked, this case should
 * never be reached. */

Another piece of information: I tried this in 2.83.5 and it worked, although it crashed when I used undo right after that.

This option should not be enabled when a linked scene is active…
