Hello, as soon as I open Zotero I suddenly get the error below, how should I fix it, thanks a lot!
Error opening input stream (invalid filename?): jar:file:///C:/Users/%E8%81%94%E6%83%B3/AppData/Roaming/Zotero/Zotero/Profiles/oweo0wok.default/extensions/Knowledge4Zotero@windingwind.com.xpi!/bootstrap.js

I also encountered this problem, and it was caused by installing the "Translate for Zotero" plugin. The problem was resolved after removing this plugin.

Are you storing your Zotero data directory in a cloud storage folder (Dropbox, Google Drive, OneDrive, etc), which is likely to break anything in Zotero, including the plugin package mentioned in your error?
