Fatal error: required ‘/home/…./public_html/wp-includes

Hi,

I have just done an update of YoastSEO plug and got the following error:

Warning: require(/home/…./public_html/wp-includes/class-wp-hook.php): failed to open stream: No such file or directory in /home/…./public_html/wp-includes/plugin.php on line 25

Fatal error: require(): Failed opening required ‘/home/…./public_html/wp-includes/class-wp-hook.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/…./public_html/wp-includes/plugin.php on line 25

I can’t login in my WP admin site, and my page displays the error message above.

What can be done to fix it?

Thank you
