Version 11.2.2.3 PHP error

Hi I just updated the PixelYourSite PRO plugin to version 11.2.2.3

However I now get critical PHP erros:

Backend fatal error: PHP Fatal error: Uncaught Error: The script tried to call a method on an incomplete object. Please ensure that the class definition "PYS_PRO_GLOBAL\\FacebookAds\\Object\\ServerSide\\Content" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide an autoloader to load the class definition in /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/vendor_prefix/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/CustomData.php:443\nStack trace:\n#0 /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/vendor_prefix/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/Event.php(354): PYS_PRO_GLOBAL\\FacebookAds\\Object\\ServerSide\\CustomData->normalize()\n#1 /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/vendor_prefix/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/EventRequest.php(343): PYS_PRO_GLOBAL\\FacebookAds\\Object\\ServerSide\\Event->normalize()\n#2 /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/vendor_prefix/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/EventRequest.php(282): PYS_PRO_GLOBAL\\FacebookAds\\Object\\ServerSide\\EventRequest->normalize()\n#3 /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/vendor_prefix/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/EventRequest.php(277): PYS_PRO_GLOBAL\\FacebookAds\\Object\\ServerSide\\EventRequest->defaultExecute()\n#4 /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/vendor_prefix/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/EventRequest.php(247): PYS_PRO_GLOBAL\\FacebookAds\\Object\\ServerSide\\EventRequest->sendToCAPIEndpoint()\n#5 /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/modules/facebook/facebook-server.php(311): PYS_PRO_GLOBAL\\FacebookAds\\Object\\ServerSide\\EventRequest->execute()\n#6 /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/modules/facebook/facebook-server-async-task.php(48): PixelYourSite\\FacebookServer->sendEvent(Array, Object(PYS_PRO_GLOBAL\\FacebookAds\\Object\\ServerSide\\Event))\n#7 /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/vendor/techcrunch/wp-async-task/wp-async-task.php(164): PixelYourSite\\FacebookAsyncTask->run_action()\n#8 /var/www/mywebsite/public_html/wp-includes/class-wp-hook.php(324): WP_Async_Task->handle_postback('')\n#9 /var/www/mywebsite/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters('', Array)\n#10 /var/www/mywebsite/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array)\n#11 /var/www/mywebsite/public_html/wp-admin/admin-post.php(85): do_action('admin_post_wp_a...')\n#12 {main}\n thrown in /var/www/mywebsite/public_html/wp-content/plugins/pixelyoursite-pro/vendor_prefix/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/CustomData.php on line 443\n

Can you help me debug this or fix the error?
