Comment (by swissspidy):

 With all the details you have given us, this doesn't sound like a
 WordPress issue at all.

 This sounds like an OPcache issue (see #36455), which means that your
 server still has the old PHP files in its cache.

 A quick workaround to solve this would be creating a file like
 `opcache.php` in your WordPress root folder with `<?php opcache_reset();`
 in it. Then, open that file in the browser (e.g.
 `https://example.com/opcache.php`) and delete the file afterwards.

 Alternatively, restart php-fpm on your server or use a WP-CLI command like
 https://packagist.org/packages/wearerequired/wp-cli-clear-opcache to do
 the same. Provided you have WP-CLI and this WordPress plugin installed,
 you would run `wp opcache clear` on the command line.

 If neither of that works. contact your hosting provider for help.
