Short description of error
File crashes Blender on open. (Also crashes the 2.80 release version)
Before this happened I was removing some animation properties that had missing paths due to renaming of a bone on a rig that was Library linked using the new Library Override system.
Exact steps for others to reproduce the error
I've attached the scene so hopefully you can get some information from the crash?
[Based on the default startup or an attached .blend file (as simple as possible)]
