Segmentation fault on export on linux

[grandemk]

Material Maker version:
1.7

OS/device including version:
Vulkan 1.4.312 - Forward+ - Using Device #1: NVIDIA - NVIDIA GeForce RTX 5070 Laptop GPU

Issue description:
Segfault and no export instead of a blender export of the material when using the batch headless mode. When I use the editor menu, it works.

Steps to reproduce:
./material_maker.x86_64 --export-material --target Blender -o ~/repo/Hephaistos/ExportMat/basement_wood ~/repo/Hephaistos/TextureTerrainPtex/basement_wood.ptex
Godot Engine v4.7.stable.official.5b4e0cb0f - https://godotengine.org
