Issue description and reproduction steps

Crash happens on loading blend file, unless if the BlenderMalt add on is disabled, I mean sometimes it still wants to crash on load, I seem to have to try a couple of times, but eventually it'll open.

Once opening, and reactivating the addon, Malt spams the system console with this error. (Have not changed rendering engine to Malt yet)

File "C:\Users\sexti\AppData\Roaming\Blender Foundation\Blender\3.6\scripts\addons\BlenderMalt\MaltMaterial.py", line 227, in track_shader_changes
    compiled_materials = MaltPipeline.get_bridge().receive_async_compilation_materials()
AttributeError: 'NoneType' object has no attribute 'receive_async_compilation_materials'

Blender locks up once switching the renderer, and attempting to enter render preview. It spams the log with references to the .malt.autogenerated folder, however, I'm experiencing this in pretty much all of my blend files, and the solution seems to be to delete the autogenerated folder and let it generate a new one.

Here's a traceback I'm getting in the system console with the crash on load

Do you have more than one scene and Malt is the selected rendererer there, maybe?

The crash happens in Blender, inside b_bone_deform . Malt doesn't touch armatures in any way, but I see a warning in your log caused by an addon called bone_selection_sets. I'd say that (or another armature related addon) is a lot more likely to be the cause, especially if it also happens sometimes with Malt disabled.

Ah it does seem to be caused by a Rigify feature set, I didn't think to try and deactivate those individually before. There were multiple scenes as well. Don't understand the bone_selection_sets thing, I've been getting it for a long time, it's not even enabled so I don't know why it's throwing anything at all. Goes away if I enable it.

Seems to not be related to Malt after all. Closing issue.
