[Error] Niagara packaging

So I’ve been working in a project and been using the Niagara particle system for some of the explosions and fire effects. I’ve tried to build the first package today to do some testings and I got this error. Can someone please help me? My particles are looking so good I don’t wanna switch to cascade right now :frowning:
