It looks like something's broken in your copy of WordPress, either wp-load.php or includes/functions.php or something else in between. Take a backup of everything, then try following the manual update instructions here

https://wordpress.org/support/article/updating-wordpress/#manual-update

to replace all of the WordPress core file with a fresh copy.
