Hello, I am getting a null ref when attempting to load a model via Assimp about 95% of the time. The other 5% it loads fine. The model is fine, loads fine in Blender or Unity, but dies out attempting to load into Ab3d via Assimp. The error is rather unhelpful so I'm not sure where to look next. The code I'm using is essentially the AssimpWpfImporterSample but in my own code. I can replicate the same issue in the PowerToys sample version. I cannot find another model with the similar problem...yet.

I am new to AB4D and evaluating this software for purchase. Any help is appreciated. Thanks!
