Rename the Addons folder by adding a character to the end. The game will no longer recognize the folder and is much faster than unchecking all addons and libraries.
For PC, the path should be in Documents>ESO>Live>Addons.
When Zenimax fixes all this, change the name back. This should keep settings in place if you have some addons disabled on some characters but not all. That makes it better than using the in-game toggle all on or off.
