Comment (by treibstoff):

 Last night, I had the same problem.
 I have a site , Elementor, wordfence, rocket and some more running (done
 by a former webmaster) and the update from 6.2 to 6.3 via WP was done with
 no problems.
 Due to inattention I delated the folder "wp-includes" via Filezilla.
 So I downladed the 6.3 package and updated the whole package (not just the
 delated includes folder) manually.
 After that I just got a white screen while trying to login...and the fatal
 error (lazyloader already in use ) as described in the first post above.
 Reinstalled 6.2 manually and everything back and fine.
 I will update once more 6.2 to 6.3 via WP... and will see if the
 settings.php is not updated.
 I let you know.
