Folders can't be accessed when copied to desktop
Hi,
I've just upgraded to the macOS to High Sierra, and immediately I encountered this problem: when I tried copying a folder containing files (movies, docs, etc.) into the MacBook desktop, it was successfully copied but the folder is not in solid colour instead it's in transparent, and I can't open it.
But if I copied the folders into another place, say like the Download folder, it's alright.
What's wrong?
MacBook, macOS High Sierra (10.13), 12-inch, Early 2017
