Comment:

 Hi @mmcalister and welcome to Trac! I suspect you're running into the same
 issue described in #59111, though the version difference from 6.3.0 to
 6.3.1 is a new detail. Would you mind trying to add the following line to
 the wp-config.php file for that site and see if your problem goes away?

 {{{#!php
 define( 'WP_DEVELOPMENT_MODE', 'core' );
 }}}
