Error ID 920022381

Zotero has completely stopped syncing and only says that an error has occurred. I have tried to remove the last uploads, but that didn't help. I don't know what happened or how to reproduce the issue, as I have just added a couple of new sources. I have a suspicion that it is connected with EPUB attachments because I think it started when I attached an EPUB file, but I am not sure.
