I am upgrading the Mediawiki installation from 1.44.2 to 1.45.1.
Everything is OK. Until I try the update script. I forgot to record the error. So I found one on the Web. As below
15:47:42 [250e8a55b4df40e8c3d5f0dd] [no req] Error: Class "Wikimedia\Parsoid\DOM\HTMLDocument" not found

It is a problem between the php8.4 and MediaWiki.
So it is just a workaround to make the upgrade continue and finish.
The problem is that Wikimedia\Parsoid\DOM\HTMLDocument isn't properly autoloaded. I solved it temporarily like this:
require_once('vendor/wikimedia/parsoid/src/DOM/HTMLDocument.php');
Insert this line right before $doc = HTMLDocument::createEmpty( "UTF-8" ); in vendor/wikimedia/parsoid/src/Utils/DOMCompat.php.
