Creative Cloud files all deleted suddenly

First, is there a topic dedicated to Clould storage  on this forum ?? Your community support page is awful in term of navigation, it's been an hour that I try to find the relevant section, and it seems that there is no general Cloud Storage topic, or it's hidden somewhere, dramtic design from Adobe imho. So I post in Photoshop...

I have a big issue :

ALL MY FILES HAVE BEEN ERASED SUDDENLY IN MY CREATVE CLOUD FOLDER, IN THE CREATIVE CLOUD BUT ALSO ON MY LOCAL DRIVE  ON MY MAC SYNCHRONIZED WITH THE CLOUD !

It just happened yesterday, everything has gone, I did nothing, no update, no transfer, nothing...

However, the creative cloud app show that there is 5.7Go of datas but nothing shop up, only few files for few Ko, but hundreds of pictures have gone. 

What's going wrong ?
