Short description of error
If I relocate a linked blend file and save (Ctrl+S) the current file, Blender crashes. I believe this only occurs if the linked collection is disabled in viewport (and it has a library overriden armature).
Exact steps for others to reproduce the error
1- Launch the provided Suzanne.blend file inside Monkey folder.
2- Right click to the broken linked file in the outliner and select relocate.
3- Go to parent folder (Alt+Up Arrow), double click Cube.blend
4- Save (Ctrl+S) and Blender will crash.
