Critical Error after Update to PHP 8

When I update my site to PHP 8, Facebook for Woocommerce produces a critical error on the site. I’ve tested with a different theme and with all other plugins inactive and it still produces this error:

Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /var/www/wp-content/plugins/facebook-for-woocommerce/facebook-commerce-pixel-event.php:544 Stack trace: #0 /var/www/wp-content/plugins/facebook-for-woocommerce/facebook-commerce.php(399): WC_Facebookcommerce_Pixel::set_pixel_id(‘350953405497932’) #1 /var/www/wp-content/plugins/facebook-for-woocommerce/facebook-commerce.php(232): WC_Facebookcommerce_Integration->init_pixel() #2 /var/www/wp-content/plugins/facebook-for-woocommerce/class-wc-facebookcommerce.php(603): WC_Facebookcommerce_Integration->__construct(Object(WC_Facebookcommerce)) #3 /var/www/wp-includes/class-wp-hook.php(308): WC_Facebookcommerce->get_integration(”) #4 /var/www/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) #5 /var/www/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #6 /var/www/wp-settings.php(623): do_action(‘init’) #7 /var/www/wp-config.php(102): require_once(‘/var/www/wp-set…’) #8 /var/www/wp-load.php(50): require_once(‘/var/www/wp-con…’) #9 /var/www/wp-admin/admin.php(34): require_once(‘/var/www/wp-loa…’) #10 {main} thrown in /var/www/wp-content/plugins/facebook-for-woocommerce/facebook-commerce-pixel-event.php on line 544
