Question about lack of reality. Did they reject Copenhagen Interpretation?!

This year's experimental manuscript appeared in arXiv that says Reality and Absolute Truth is absent:
https://arxiv.org/abs/1902.05080
I was trying to find this manuscript a weak point. How does it satisfy (or not) the Copenhagen Interpretation?

They like to fight against own existence – against Reality, e.g.:

"What If We Detonated All Nuclear Bombs at Once?"


"New findings have physicists questioning reality,"


Michio Kaku: Will Mankind Destroy Itself?

This is what happens when people forget physics is a construct we use to help us understand specific aspects of the world and think it can answer things it was never supposed to answer.

Look who's back.
