The value of content:encoded of the failing podcast looks like the following:

I think this RSS feed is improperly formatted but we can still work with it.

This is what the content:encoded looks like:

<content:encoded>Die 
                <a href="https://daswarschonkaputt.tech/post/27/">SHOWNODES </a> findet ihr auf unserer Website https://daswarschonkaputt.tech
</content:encoded>

But html should be wrapped in CDATA like this:

<content:encoded>
                <![CDATA[<p>One of the last uncontacted people in the world live in the Bay of Bengal and they have made it clear they don&rsquo;t want you to visit.</p><p>See <a href="https://omnystudio.com/listener">omnystudio.com/listener</a> for privacy information.</p>]]>
