3Ds crashes when loading material from library

[Bruno Thiago Rego Valeriano Silva]

Hello!

I've created a 3Ds max library (.mat file) and saved a material that used a susbstance2 node.
The problem I'm having is that when I try to create a instance of that material, 3Ds max crashes.

Versions:

• 3Ds max 2021.2
• Substance plugin 2.4.0

sbsar file: https://share.substance3d.com/libraries/709

Steps to reproduce:

• Open a 3ds max project
• Load sbsar file with substance integration (batch import)
• Substance to a named pbr (metal/rough) material such as gray granite
• Open a previously created material library such as "my_library.mat"
• Save the "gray granite" material to the library and save the library
• Close 3Ds max and open it again with the same project
• Try to create a copy of the "gray granite" material from the library on the slate material editor

Any idea if that's a workflow problem? Path characters? Or is it really a bug?

Other tasks are also making max crash:
1. Reload a substance; and
2. Bake the textures

Hope someone can help me here.
