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…

[image] abdo: Anki used to handle this “Uknown error” by catching and ignoring it , but it appears this is no longer the case after this change . @dae was this intended? Looks like a mistake. Thanks for catching it! I’ve pushed a fix.
