Worked: not so much 'worked', but it didn't crash in 2.83
Short description of error
A custom property on an armature bone drives the amount of children particles on an object. Linking the collection of object and armature, and using Library Override will result in a crash when entering Pose Mode.
Exact steps for others to reproduce the error
- Start new blend file
- Link in collection 'Hairball' from attached blend file 'CustomPropery_ChildrenParticles'
- go to menu Object->Relations->Make Library Override
- select the armature object, enter pose mode & select the bone
