When trying to update metadata I keep getting the below error which I have never seen before. It also shows up when I try to open books. I'll also note that windows explorer is not open in the folder in question. I've tried exiting calibre and restarting it as well.

calibre, version 6.25.0
ERROR: Cannot open file or folder as it is in use: Could not change on-disk location of this book's files. The folder "C:\\Users\\user\\Calibre Library\\AuthorName\\Book Title (5135)" is opened in another program, so calibre cannot access it.This is usually caused by leaving Windows explorer or a similar file manager open to a folder in the calibre library. Close Windows explorer and retry.
