Hi there,
Zotero standalone updated itself from 5.0.78 to 5.0.79 a few minute ago, but failed. And now I couldn't access to my database.

Besides, the language was set to English. After this failed update, it rolled back to Chinese and the term "intl.locale.matchOS" at "about:config" disappeared.

I would appreciate it if anybody could give me a hint.

My system is win10 X64.

There is the error report,
[JavaScript Error: "key_manager_1.KeyManager is undefined" {file: "chrome://zotero-better-bibtex/content/BetterBibTeX.ItemPane.js" line: 29}]
