I think this might be due to the complexity of some materials for Eevee. Some procedural fabric materials we have in the database have far too many nodes, and Blender just crashes trying to process them. The weird thing is this happens with a GTX 1080.
I'm working on a fix, that basically hides more complex materials from EEVEE.
This however points to some deeper issue with shaders processing/compilation, that probably isn't connected to the addon. The addon technically just downloads the file, appends the material and links it to the mesh.

This is on TODO list where displayed Materials will be limited for EEVEE - complex materials won't simply be displayed there and there will be a warning. As of now, this isn't blenderkit bug - it's most probably EEVEE crashing because of too complex material setup.
