I am facing with below error immediately after updating my Zotero 7 to a new beta version 69+56c363521. I reinstalled Better Bibtex (the plugin which the error is related to), but the error still remains.

The error message:
@jar:file:///C:/Users/zarar/AppData/Roaming/Zotero/Zotero/Profiles/l7mv6619.default/extensions/better-bibtex@iris-advies.com.xpi!/bootstrap.js:40:12

I attempted to download an older beta version of Z7 from below link:
https://www.zotero.org/support/beta_builds?do=revisions

...however, every time, despite using different download links, I end up downloading the same file instead of older Zotero beta versions. Any solution for the error message or are there mirror links where I can download the previous versions of Zotero 7 beta.
