ue4 4.24 Hair system bug (the ue4 editor does not respond when choosing GroomAssetSystem)

I have some trouble , in UE 4.24 , I took all the documentation steps for importing the Alembic hair into the UE4, but there was such a problem - after the hair was added to the character’s skeleton and the “add component” - Niagara systems, in the Niagara Asset tab - the editor does not respond when you select the Groom Asset systems and does not respond to my actions at all, hair material - default , screenshot attached ,
