Error after Upgrade to PHP 8.2.5

After Upgrade from PHP 7.4.33 to PHP 8.2.5 I have the following error message on the page:

Warning: Trying to access array offset on value of type bool in /home/httpd/vhosts/myhosting/httpdocs/traeffpunkt/wp-content/plugins/easy-facebook-likebox/facebook/admin/includes/efbl-skins.php on line 126

And the following error in the WP Backend:
