There is a new UI string (ID#2651490 on l.d.o) appeared in 8.6.x :
No front page content has been created yet.<br/>Follow the <a target=\"_blank\" href=\"https://www.drupal.org/docs/user_guide/en/index.html\">User Guide</a> to start building your site.
Basically, I welcome the idea to point admins of freshly-installed Drupal sites to the User Guide frontpage, which are now being translated into a dozen of languages, so the link target URL can be localized as well. Great!
However, when the l10n_update module imports the .po files, then this string causes parsing error with its HTML line break element <br/> between its two sentences. As far as I tested out with two .po files containing only this string alone, I found that the per sign ("/")
As it can be seen the German localization team solved the issue by simply removing the "/" char from their translation. In Hungarian I also submitted an other variant to see whether it will seamlessly import next time?
Regarding MDN writes in the "Tag omission" section:
"Must have a start tag, and must not have an end tag. In XHTML documents, write this element as
<br />".
So the proper format of this HTML element is with an extra space before the per sign, so I plan to attach a patch to remove it from the string.

No visible changes on UI.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
It looks like this been fixed, by updating the strings on the front page, splitting them up:
<em>You haven’t created any frontpage content yet.</em>

I no longer see this issue in Drupal 10.1, and am closing this issue.
