The RSS namespace identifier in the lxb-librarian feed was renamed from xmlns:lxb to xmlns:lxbLib. The xmlns:content module was also added to the feed declaration.

Before:

<rss version="2.0" xmlns:lxb="https://lexblog.com/lxb-librarian">

After:

<rss version="2.0" xmlns:lxbLib="https://lexblog.com/lxb-librarian" xmlns:content="http://purl.org/rss/1.0/modules/content/">

If your parser references the lxb namespace prefix, update it to lxbLib.
