For what it's worth, I've experienced this issue a few times. After a windows 10 update (and of course the required reboot) calibre doesn't launch. What resolves it for me is just a reinstall of the last version installed. I just relaunch the Windows installer; I can't remember whether it offers a repair option or not, but after that calibre does relaunch.
