Just happened again with another book. It's taking all that time at the "preparing book for first read" task. According to Task Manager, nothing much is running (the Calibre stuff is taking the most resources (though they're a miniscule amount)). Nothing fails, so there's nothing in Windows' Event Viewer. Closing the viewer and immediately re-opening takes the normal couple of seconds. Closing the viewer again, editing the epub, removing the viewer bookmarks file, saving and re-opening the viewer takes the normal couple of seconds.
I'm pretty much stumped for what could be causing this and how to track it down. Perhaps it's a Windows 11 issue. I'll stick my system information here and maybe over time other people will run into the issue and can use it as a comparison:
