I am running Calibre 7.10 on a laptop running Windows 11. Calibre is the portable version running on a portable hard drive connected to the laptop. I have my libraries split over 21 'sub' libraries for convenience.
I recently had to rebuild my main Calibre library which exists on the drive with all my other libraries but it will not now recognise my main Calibre Library file.

I decided to create a blank library and then import all my books from the rebuilt Calibre library. However when I open up the calibre program it immediately starts a job trying to get a list of books from a device and, if it is left to continue, takes forever (I never let it go further than two days). The job cannot be stopped by 'Stop selected jobs., it says 'Cannot kill jobs that communicate with the device'. I do not have a device (like a Kindle) attached at this time so am confused by this issue and obviously need help to get out of this quandary. I have been a user for many years but recently my laptop has not helped my humour as well as being in my 80th year! Most of my life (since the early 80s) has been involved with computers on different levels (System Analyst, IT Manager etc).
