Witcher 3 suddenly dont run from steam

Hi,
I am using Manjaro xfce and I have installed steam and witcher 3 always worked here.
Now somehow, steam after clicking on play after one second stops.
The console output is:

What happened there and how to fix it? I would be grateful for any leads, I have quite many hours there and saves.
