I tried to update my wordpress installation using auto update feature. After update the entire site is down. Checking the log file I have this error:
Fatal error: Call to undefined function apply_filters() in /public_html/wp-includes/load.php on line 317
I found this github issue. But they refer to solving the issue for installation that uses wp-cli. Any help would be appreciated.

This problem was caused by the wp-settings.php. Due to permissions trouble this file was not updated while using auto-update. Replacing this file with the latest wp-settings.php solved the trouble.
