System Information
Operating system: windos 10
Graphics card: 1070

Blender Version
Broken: 2.83
Worked: 2.82

After duplicating these nodegroups they somehow got corrupted and started crashing blender. They were much more complex groups when I duplicated them, I simplified them as much as possible but the effect is still the same. I do not know how to replicate the corruption itself with simpler groups.

Try copy pasting the object in this file or materials or appending them it will crah Blender

Can confirm crash, missing links in ListBase.

So lib_id_library_local_paths is called with lib == NULL. Not sure if this is the root issue here.
