problem importing .fbx character/animations

I’m using Daz Genesis model, the model itself imports fine into engine. When I add animations in MB, the asset works fine in .fbx preview but when I try importing into engine I get can not import/can not create asset error. Can anyone tell me why and how to fix

if i save the character and a take in 3d max it works fine? but i can only save 1 take with the character.
