I am working on a client site, In the wordpress theme file I have added a cron.php file to perform some cron job functions. It was executing fine without any issues till last few days. When I checked The cron file execution is not happening when I try to execute the file from server I got an error
PHP Fatal error: Uncaught TypeError: ftp_nlist(): Argument #1 ($ftp) must be of type FTPConnection, null given
in wp-admin/includes/class-wp-filesystem-ftpext.php:438
Stack trace:

When I checked for the solutions after going through some multiple sources I found adding define('fs_method', direct) could fix the issue, I have added that and set the ownership and permission through server using this
sudo chown -R www-data:www-data /path/to/wordpress
find /path/to/wordpress -type d -exec chmod 755 {} ;
find /path/to/wordpress -type f -exec chmod 644 {} ;
chmod 775 /path/to/wordpress/wp-content/uploads/wc-logs
For a while the issue seems to be fixed and the cron jobs where done without any problem, after few hours I started getting these warnings on the site
PHP Warning: touch(): Utime failed: Operation not permitted
in wp-admin/includes/class-wp-filesystem-direct.php on line 529
PHP Warning: chmod(): Operation not permitted
in wp-admin/includes/class-wp-filesystem-direct.php on line 173
When I set the permissions and ownership again the issue will go for a while but keeps happening after some time. Need a proper fix for the issue gone through multiple forums and blogs and the solution I get is the same.
WooCommerce flagged the error as a bug https://github.com/woocommerce/woocommerce/issues/58985
