Hello everyone,

I’m facing a recurring issue with Zotero 8.0.1 (x64) on Windows 11 (build 26200) related to PDF attachments added via the Zotero Chrome Connector.


Whenever I save a PDF using the Chrome Zotero Connector, Chrome shows that the file has been successfully downloaded.

The reference appears in Zotero, but when I try to open the PDF, Zotero reports that the file is missing.

After this happens once, all files in that attachment folder stop showing up inside Zotero (even though they still exist on disk).

If I restart Zotero, everything returns to normal and all files reappear correctly.

This cycle repeats the next time I download a PDF via the browser connector.

It seems to trigger specifically after downloading PDFs via the browser connector, not when attaching files manually.

Here is the report from Zotero

What should I do?
