Comment (by apermo):

 Hey @kkmuffme I ran into a similar issue via our sentry.

 Mine throws `Deprecated: preg_match(): Passing null to parameter #2
 ($subject) of type string is deprecated`

 in https://core.trac.wordpress.org/browser/tags/6.7/src/wp-includes/class-
 wpdb.php#L3819
 {{{#!php
 <?php
 if ( preg_match(
 '/^\s*SHOW\s+(?:TABLE\s+STATUS|(?:FULL\s+)?TABLES)\s+(?:WHERE\s+Name\s+)?LIKE\s*("|\')((?:[\\\\0
 -9a-zA-Z$_.-]|[\xC2-\xDF][\x80-\xBF])+)%?\\1/is', $query, $maybe ) ) {
         return str_replace( '\\_', '_', $maybe[2] );
 }
 }}}

 In my case I can follow the trace down to a `update_option()` where it
 ultimately begins, so I think this is exactly the same issue as yours and
 should be covered by your PR.
