Whenever I select the a file in File Explorer, regardless of whether I'm trying to do something with that file or trying to make it the first of a set of files, the PC comes up with a message that says "Sorry, something went wrong and Word was unable to start (24)", even though I wasn't trying to run Word. I don't know whether this is connected to, or the cause of, the problem above, whereby it doesn't let me select multiple files.
