Creative Cloud files corrupted

This is a picture of how a LOT of my files appear on my pc. (some 500+ files) I have tried numerous times to repair them ofcourse, and have searched the internet but apparantly I am the only one with this problem...? I can't believe that, so I am hoping there is somebody here with the answer!
All files suddenly have the Illustrator logo, even when its a Indesign of PDF or whatever. And they are 1 kB, so all content has disappeared. I work with a PC in the office, and on a Mac at home. Maybe it has to do with switching between these two computers? Hope to find an answer here, thank you so much!
