Yes, obj can store only simple models. To read skeletal animation you will need assimp importer.
What file format are you using? Maybe you can try to save into another file format - fbx and dae (Collada) should both support skeletal animations.
The assimp library is constantly under development. Therefore I have got the latest version from GitHub source and compiled it. When I tried to use that with the skeletal animation that is part of the Ab3d.PowerToys samples I got the same exception as you got. So it looks like there is some bug in the latest source of a breaking change.
I do not get that exception when using the assimp library that comes with the Ab3d.PowerToys library.
So I have another question? Do you also use a newer version of assimp library? If you do, then try with the official v5.0 that also comes with Ab3d.PowerToys library.
