Ccleaner deleted my desktop with almost everything in it

I'm still traumatized, happened just now. why would ccleaner behave that way?

my desktop is not in my primary partition, got SSD on C drive and my user folder is in E:\\sys\user

my only logic explenation is that it treated my user folder and the dektop thats in it as temp files, what the actualy f***?!

as u can see folders gone from desktop, pinned shortcuts gone from taskbar, my chrome lost all the extendtions, just what the f***..
