I am having the same issue with my sites.
PHP Notice: Undefined offset: 173 in public_html/wp-content/plugins/wordfence/vendor/maxmind-db/reader/src/MaxMind/Db/Reader/Decoder.php on line 87
Also when I go to the settings page essentially all resources get a 404 error.
And reinstalling using wp-cli didn’t help
Downgrading worked to get the site back online.
wp plugin install wordfence --version=7.1.11 --force
