Previewing beats guessing here, because the failure mode is silent. A title truncated at 60 characters or an OG image with the wrong aspect ratio does not throw an error — it just quietly underperforms.

Disallow does not mean "keep it out of the index"
A robots.txt Disallow tells a crawler not to fetch a URL. It does not tell a search engine to leave it out of results. If other pages link to it, the URL can still be indexed — listed without a description, because the crawler was never allowed to look inside.
Worse, the two directives conflict. To keep a page out of the index you need a noindex meta tag, and a crawler blocked by robots.txt can never fetch the page to see it. So blocking a URL in robots.txt actively prevents the removal you wanted. Allow the crawl, serve noindex, and remove the block only once the page has dropped out.
Two more things it is not. It is not a security control — the file is public and lists exactly the paths you consider sensitive. And it is advisory: well-behaved crawlers respect it, hostile ones read it as a directory of interesting targets.
