When starting the Books app I get the following error message:
Apple Books Can't Access Your Library
Make sure the disk containing your library is connected, then click Try Again.
Library Location: (null)
You can also reset your library, then sign in to view and re-download your purchased books.```
How can I reset the location? Clicking on "Reset Location" does nothing.
I found the library with the books still there, but there is no way to set the location.
Running Mojave 10.14.6
