Workflow no longer works after Mac update, help needed to export Scrivener to Word with live citations

All of a sudden, Docdown is no longer recognising citations. I have a chapter written in Zotero without a way to render them. I’ve now installed Pandoc and I have a reference file etc. Could someone please recommend a simple guide to follow to get my work out of Scrivener with citations… I think I’m just going to have to go back to Word. The fear of losing everything is real!
