Short description of error
Blender crash when making a library override on a rig or mesh with rig, if not, blender crash when you try to pose the character

Exact steps for others to reproduce the error
1 - Create a Blender file with a rigged mesh.
2 - Link the collection of the rigged mesh in another blender file.
3 - Try to create a library override on the rig or the mesh
4 - If blender didn't crash try to pose the character and pressing Ctrl+Z

(The error seems to have a little randomness)
When Blender don't crash the mesh has lost their weights

Override on Rig in a linked collection worked for me, but after having an override on the Rig, selecting the Mesh: As soon as you hover the Menu Object>Relation Blender crashes.

Tried the same under MacOS. 2.81 from blender.org. Crashed the same way. crash.txt gave me the following:

Same. Crashing when I try to change material for any linked object. Library Overrides doesn't work in outliner. And I didn't found how override modifiers - I can only to add new and then it crashes...

I think this issue got fixed by T71741.
So one open bug less.
