I cannot delete a folder on my desktop, I get a message saying 'could not find this item'

I had a folder on my desktop which contains alot of files, ranging from videos, images, etc. I turned on my laptop one day and the folder had nothing inside of it apart from a few other empty sub folders. Not only have I lost all of the content in the folder, I now cannot delete the folder either, I get a message that says 'Could not find this item'. (see pictures)

The message will go away after you restart the PC.

I have already tried this and basic troubleshooting methods, this side not work.

Sorry, but I ran into the same folder deletion problem and in my case, rebooting the PC cold fixed the issue.
