Hi,
Since this started immediately after updating Gutenberg, the first thing to confirm is whether this is a real plugin conflict or a hidden panel / JavaScript error.
Could you share:
- WordPress version
- Gutenberg version
- Yoast SEO version
- theme name
- whether this happens on all posts/pages or only some
A good way to isolate it is:
- Temporarily deactivate the Gutenberg plugin and test the core editor. If Yoast analysis returns, that points to a Gutenberg plugin regression.
- If possible, use Health Check & Troubleshooting so you can test with only Gutenberg + Yoast active and a default theme, without affecting visitors.
- Open the browser console and check for JavaScript errors in the editor, because a JS error can cause Yoast analysis panels to disappear.
- In the editor preferences/options, check that the Yoast panel has not simply been hidden.
If you can share the exact versions and any console errors, it will be much easier to narrow down whether this is Gutenberg-specific or another plugin/theme conflict.
