I degraded zotero to 5.0 version after an upgrade to 6.0 version and now external links only open zotero but won't locate the exact literature and open the pdf.

Here is my link:
[Lee et al 2020:2000038](zotero://open-pdf/library/items/7QVR82QZ?page=2))

The error is:

[JavaScript Error: "Component returned failure code: 0x80520001
(NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsIFile. initwithPath]" \{file: "chrome://zotero/content
/xpcom/utilities_internal. js" line: 822\}]

Would anyone help me with this problem? Thanks.
