Start at Assimp.AssimpContext.ImportFile and follow the stack through Scene.FromUnmanagedScene, EmbeddedTexture.FromNative, and MemoryHelper.FromNativeArray. Reproduce the failure with the FBX file and texture configuration described by the report, then determine why scene texture marshalling fails and verify that the file imports successfully.
