Calibre 7.19.0 has crashed on Windows 10 and won't restart.

[Evaeiqua]

Calibre crashed on me today and won't restart. I rebooted to no avail. I downloaded the installation file and tried to repair Calibre. That didn't work. I uninstalled and reinstalled Calibre 7.19.0 and no luck. Any suggestions would be great.

I tried calibre-debug -g and got this response.

What happens if you try to launch in Windows' safe mode?

[DiapDealer]

calibre-customize --disable-plugin Goodreads

DiapDealer - I tried it and got this:

ownedbycats - I tried safe mode and still nothing. Calibre stops during loading.

[DiapDealer]

Double check the plugin name with:

calibre-customize --list-plugins

If you still can't disable the plugin with the correct name, try uninstalling it with:

calibre-customize --remove-plugin <correct plugin name>

[kovidgoyal]

This isnt plugin related, according to that debug log something is interfering with calibre before it even gets to the stage of creating its UI long before plugins are even loaded. I am very surprised that this would occur in Safe mode as this is almost certainly some program on the computer interfering with calibre. The log indicates the QApplication object was constructed and then it has hung.

Try temporarily disabling the antivirus and also trya clean reinstall that is un-install, delete c:\program files\calibre2, then re-install (this wont affect your books/settings)
