The URL is declared in robots.txt but does not return a successful response.
Consequence. Crawlers find nothing at the address they were pointed to, so no URLs are submitted. This is worse than declaring no sitemap, because the declaration suggests discovery is covered when it is not.
If that is not intended. Publish the sitemap at the declared URL, or correct the URL to where it lives.
A meta robots tag or X-Robots-Tag header instructs crawlers not to index this URL.
Consequence. The page will be dropped from search results. That is the correct mechanism for removing a page — worth confirming it is intended for this URL.
If that is not intended. If the page should rank, remove the noindex directive. Keep the URL crawlable either way, since a crawler must fetch the page to see the change.

Notice
Every URL is open to every crawler
The file declares user agents but no effective Disallow rule.
Consequence. Every URL is crawlable, including any that exist only for internal use. Crawl budget is spent evenly rather than on pages worth ranking.
If that is not intended. Consider disallowing sections with no search value — internal search results, faceted or parameterised URLs, cart and account pages.
