I am attempting to install Wordpress on a brand new server I opened. But I'm getting the following warnings/errors when I visit the install page:
[18-May-2023 01:26:09 UTC] PHP Warning: preg_replace(): Compilation failed: unrecognised compile-time option bit(s) at offset 0 in /var/www/html/wp-includes/class-wpdb.php on line 1535

After doing some error logging, I realized the fatal error is simply a result of the preg_replace() issue.
A similar question and other reading suggested that updating the libpcre2-8-0 package was the solve. I confirmed that package is on 10.40 and there are no pending updates I can install for any pcre package (On my system its called pcre2). According to this thats the latest version.
Is there anything I can do to fix this?
