Can't login on one of my characters. The issue is exactly the same as in the now-closed thread: https://forums.elderscrollsonline.com/en/discussion/643031/pending-data-load-error-7755651-c000000000cac79.

The character was logged out while in Cheesemonger's Hollow (Volendrung tutorial) in Cyrodiil. My very first reaction was to try repair the client, to no avail, so I am currently effectively blocked from using that character.
