I recently received 2 reports from (Windows 10) users that sent me nearly identical bug reports, saying that Anki wouldn’t start with an “Unbekannter Fehler” (unknown error) from time to time. It seems like the newer version of Anki isn’t able to tell what exactly crashed in one of these addons, see below.
I will try to find out which addon is responsible for the crash.
