404 error instead of sitemap?

Question

htaccess

The essence is this:
There is a page in the admin panel - a sitemap with url = sitemap
There is a sitemap in xml-format.
So, if the xml file name matches the page url, a 404 error is displayed.
What could be the problem?
Error text:
Not Found
The requested URL /sitemap.xml/ was not found on this server.

RewriteRule ^(.*)$ /public/$1

Remove slash before publicRewriteRule ^(.*)$ public/$1

RewriteCond  %{REQUEST_FILENAME} !-f # не файл
RewriteCond  %{REQUEST_FILENAME} !-d # не папка

Remove comments or move them to a new line.

# не файл
RewriteCond  %{REQUEST_FILENAME} !-f
# не папка
RewriteCond  %{REQUEST_FILENAME} !-d
