I found this error message showing up on my website. fixed by updating your plugin code

Warning: Undefined array key 0 in /var/www/vhosts/connect.providencecare.ca/httpdocs/wp-content/plugins/buddypress-docs/includes/theme-bridge.php on line 384

Warning: Attempt to read property “content” on null in /var/www/vhosts/connect.providencecare.ca/httpdocs/wp-content/plugins/buddypress-docs/includes/theme-bridge.php on line 384

I fixed it by this, I hope you can fix this issue on the next update.

Update this code
$rendered = do_blocks( $templates[0]->content );
to:
if ( empty( $templates ) || empty( $templates[0] ) || empty( $templates[0]->content ) ) {
return $templates;
}
$rendered = do_blocks( $templates[0]->content );
