Material Library makes 3ds crash

Hello there,
i’m facing crashes of 3dsmax when I use the material library…

Often, just applying a shader to selected objects, it crashes for no reason…
It happens often, on various scene, in the example below the object is a simple box…

It’s boring as I need of course to save my scene each time I will use the library, but also bc there is no visible reason for this to crash for me…

Just wanted to report this…

See you

Is this Corona version 6 hf1-2, or an earlier version?
