[Crash] 4.4.1 - Material Editor crash using Copy/Paste

UE4 crash when I Copy/Paste nodes in the material editor.
happens evry time I try to paste (Ctrl+V) nodes (one or more) in my project, so right now I can’t use Copy/paste,I can only duplicate nodes but duplicate don’t work if I want to move part of my nodes to others mats/MF. very frustrating…
happens in evry material of my project. Not happens in others projects.
