This is what ChatGPT says:
 Where could the problem be?
1. The Language Filter plugin changes the URL

The System - Language Filter plugin adds a language to the URL (e.g. /en/article.html instead of /article.html).
Therefore, if $ucanonical_encoded is generated without language and the current canonical already contains a language - they will not match and unset() will occur.

💥 As a result:

canonical is deleted,
but a new one is not added (if $addRel = false is not reset correctly somewhere outside this fragment or the insertion of canonical is broken further down the code).

I hope this helps.

So, what next?
I compared file /components/com_flexicontent/classes/helpers/html.php
with same file from master branch - no changes.
