Ran into the same issue. It seems to be happening because the title separator is outputted as an entity name (eg –) instead of entity number (–) – at least in Custom Post Type feeds.
A similar issue was reported and fixed about two years ago.
Tested with the latest Yoast version, 19.14 and 19.13.
I dug a little deeper to find out the possible cause for this.
It looks like the use of pre_get_document_title filter short-circuits the wp_get_document_title , which has filter document_title_separator.
That document_title_separator filter is used on feed-imporvements.php file to decode entities. But since the whole title generation is short-circuited, said filter is never used.
The following code, added to the theme, fixed it for now.
add_action( 'get_wp_title_rss', function( $title ) {
return html_entity_decode( $title );
} );
I believe Yoast should do something similar in feed-imporvements.php instead of using document_title_separator filter.
Hello @antcrescendo
I’m sorry abpout the declaration error in your sitemap. This happens when an empty whitespace or a blank line appears due to a conflict with another plugin or your theme. Usually, there is an empty space or a blank line before or after the closing PHP opening or closing tag, which shouldn’t be there.
You can narrow down the exact source of conflict by performing a conflict check. Once you have identified whether your theme or a plugin causes the issue, please contact the developers of that theme or plugin for assistance in finding and removing the white space.

Hello @maybellyne, I created a troubleshooting test environment with the “healthcheck and troubleshooting” plugin and Yoast is the only plugin I have enabled, but it still gives me the same error when I preview my XML sitemap.
Although I disabled all of the plugins to rule out any potential conflicts, it appears that I am still encountering the same XML sitemap error.
List of plugins: https://postimg.cc/MMPzznbt
You will see in the screenshot above that all my plugins are disabled besides Yoast and the Health Check plugin.
I am also using the Twenty Twenty-Two theme version 1.3
Yoast Version 19.14
I do have the same problem with – I run wordpress version 6.2.2 , yoast version 20.8
For the moment I fixed the trouble with the solutions provided by @sippis
Thank you Timi Wahalahti !
Had the same problem with – title separator. Either choose normal dash or use the temporary workaround provided by @sippis
Both solutions worked for me.
Thanks!
