Can you reproduce problems in Troubleshooting Mode (Help → "Restart in Troubleshooting Mode…”), which disables all plugins?

You didn't answer my question.

But this is definitely incorrect, and may have been caused by one of the many plugins you have installed:

[JavaScript Error: "'extra' is not a valid field for type 'annotation'" {file: "chrome://zotero/content/xpcom/data/item.js" line: 793}]
