Hello, I had a similar message on start up and,on the suggestion of Structure and Jimmy1 , I opened the following: Pose 12>Runtime> python> Poserscriipts> Addons and deleted the file related to DSON. I also did this for any imported runtimes particularly those from 'My DAZ Sudio' (I used to get three identical messages in the same window). The messages no longer appear.

Most of my DAZ purchases work OK but not the Genesis figures.
