Windows 10 had a few Security Definition updates a few days ago and my Calibre started with the hanging issue.

After trying some other stuff and finding this thread, I removed gui.json and global.py.json because those were the only two files updated in AppData\Roaming\Calibre since my Calibre stopped working. Doing a Windows 10 Settings>Apps>Calibre>Modify and a Repair didn't cut it. So I resorted to an uninstall/reinstall and voila! Calibre is running again.

Prior to that, I had tried uninstalling and reinstalling Calibre 4.23 and 5.9, ran an sfc scan, went through a Cleanreboot process, uninstalling and reinstalling Calibre 4.23 and 5.9 again.

All that is to say, thank goodness for this thread!!
