Try:
– deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
– switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins).
I will do that for sure, but… There is a cache somewhere between WP and W3C validator. Even if I apply some changes (i.e. publish an article, turn on some RSS formatting plugin) the W3C keeps the old version of feed for a long time. That makes such examining proces somehow hard. When I check the RSS feed in the browser all the changes are there but on W3C they have their own memory for the feed or something. I will try to switch off what’s possible and post about the effects.

Issue resolved – there was a code of a symbol invisible in WP editor between words in the post content. I was able to see it after pasting the content to txt editor outside WP. I discovered it by Chance, so if you see that when you put a cursor in a white space between words and the arrow on keyboard needs to be pushed twice to move the cursor – there must be something invisible in your post content code. Copy it, and check out in txt editor outside WP.
Error description from W3C RSS validator:
XML parsing error: <unknown>:627:88: not well-formed (invalid token)
and the line 627:
<p><strong>– szerokie tylne słupki ograniczają widoczność do tyłu • jak w niemal każdym kombi tylna szyba łatwo się brudzi.</strong></p>
Seems valid? Nope 🙂 If you get this kind of an error, have a check your content in outside WP text editor.
Best to all,
Mike
