Animation Import fails - "There is no geometry information in mesh"

Hi guys,
i’m getting a bit frustrated here as i’m trying to import animations into unreal. I have a base fbx with the model which imports just fine. But my animation fbx files all produce the error “there is no geometry information in mesh”. Any ideas how to fix that ? What i’m doing wrong ? I’ll click import, choose the fbx, on import settings choose “as skeletal”, pick my already imported skeleton below, tick import animations and hit import… seems to fail all the time…

I tried animations from Mixamo, from other models. It appears i cannot import any animations at all.

i’m having the same problem please help
