treeit mesh (.obj) crashes

thank you dear developers for adding this feature i really wanted this but there is a problem, whenever i try to add any obj files the app crashes without any error notes... (i make my obj files in blender) and when i want to export it there are bunch of options which i dont change them...maybe i have to change some of them?

here is the link to the crashing video:

anyways .obj is great but fbx is better but if obj works then i dont need fbx files and again thanks for this great app
