I got surprised that, my fresh website sudden installed this plugin automatically. Even i never seen their name ever. They hide the plugin from WP Plugin list and uses as core plugin and uses option on WP Setting. Offering premium plan and doing huge spam. I recommend WP to remove their plugin for doing spam marketing and fraud install.
A PHP session was created by a session_start() function call. This interferes with REST API and loopback requests. The session should be closed by session_write_close() before making any HTTP requests.
on the file wpcaptcha.php you should fix line 40 to 44 with this
if ( !session_id() )
{ session_start( [ ‘read_and_close’ => true, ] ); }
I had to find it my way out
