PHP Warning

After upgrading to WordPress Core to 6.9, I get the following error message:

Warning: Undefined array key 7180 in /code/wp-content/plugins/shortcodes-ultimate/freemius/includes/class-freemius.php on line 9997 Warning: Trying to access array offset on null in /code/wp-content/plugins/shortcodes-ultimate/freemius/includes/class-freemius.php on line 9997 Warning: Undefined array key 7180 in /code/wp-content/plugins/shortcodes-ultimate/freemius/includes/class-freemius.php on line 14951 Warning: Trying to access array offset on null in /code/wp-content/plugins/shortcodes-ultimate/freemius/includes/class-freemius.php on line 14951 Warning: Undefined array key 14958 in /code/wp-content/plugins/shortcodes-ultimate/freemius/includes/class-freemius.php on line 9997 Warning: Trying to access array offset on null in /code/wp-content/plugins/shortcodes-ultimate/freemius/includes/class-freemius.php on line 9997 Warning: Undefined array key 14958 in /code/wp-content/plugins/shortcodes-ultimate/freemius/includes/class-freemius.php on line 14951 Warning: Trying to access array offset on null in /code/wp-content/plugins/shortcodes-ultimate/freemius/includes/class-freemius.php on line 14951

The site is a multi-site on Pantheon.
