Description

I am opening this Issue as a counterpart to https://github.com/LuxCoreRender/LuxCore/issues/658 in order to sperate Blender- and Core-specific reports.

Starting with the following description posted on other Channels:

In BlendLuxCore v2.10 for macOS (Apple Silicon), LuxCore makes Blender instantly crash once you've got one material linked across multiple objects, then click on the Copy button in the material editor to make a material unique.

The crash also happens when you delete a material from an object, then try to paste a copied set of nodes from a different material into a newly created material.

Research direction

Start by reproducing the crash in BlendLuxCore v2.10 on macOS with Apple Silicon using the material editor: copy a shared material, delete a material and paste copied nodes, and render. Compare the behavior with the related LuxCore issue 658. Done means these material operations and rendering no longer crash Blender.
