I added this code to generate the attachment_metadata array while making sure that the serialization is correct:

		//Get function which checks whether serialization was correct
		if(!function_exists("serialize_corrector")) {
			function serialize_corrector($serialized_string){
			// at first, check if "fixing" is really needed at all. After that, security checkup.
				if ( @unserialize($serialized_string) !== true &&  preg_match('/^[aOs]:/', $serialized_string) ) {
					$serialized_string = preg_replace_callback( '/s\:(\d+)\:\"(.*?)\";/s',    function($matches){return 's:'.strlen($matches[2]).':"'.$matches[2].'";'; },   $serialized_string );
				}
				return $serialized_string;
			};
		}
		// Get the images in the attachement table
		$all_images = $wpdb->get_results($queryUnoptimizedPicture);
		
		foreach($all_images as $image){
			$tmp = array();
			$tmp['ID'] = $image->ID;
			
			if (isset($image->file_meta)) {
				$tmp_serialized_file_meta = serialize_corrector($image->file_meta);
				$tmp['attachment_metadata'] = unserialize($tmp_serialized_file_meta);
			}
			else {
				$tmp['attachment_metadata'] = array();
			}

Now I’m getting the following warning in the log when I try to optimize an image:
PHP Warning: file_get_contents(https://par2.static.resmush.it/<path&gt;.png): failed to open stream: HTTP request failed! HTTP/1.0 503 Service Unavailable
in <path>/plugins/resmushit-image-optimizer/classes/resmushit.class.php on line 92
On the UI no error is shown, it’s just shown as processing and nothing happens
