Purple (pink) textures are not caused by the addon. This is probabaly a known Blender issue that happens on some systems when OpenGL fails to compile complex shaders.
Fix (takes 30 seconds):
Go to Edit → Preferences → System → Display → Graphics Backend
Switch from OpenGL to Vulkan, then restart Blender.
This is a Blender-side rendering backend problem and has affected many users across different addons and projects. Once Vulkan is enabled, the materials work normally again.
If you had contacted support first, this could have been resolved before writing a review.
