Laravel Job Withcount Parameter not Accessible in job Laravel 5.6

Hii I created a job to send mail. I execute a query in the controller using withCount() and am able to get the count parameter inside the controller but while I am parsing the same data to the job and assign to a local variable in constructer then I use a local variable inside the handle method count parameter was missing in my local.

I am using SYNC as QUEUE_DRIVER and code files below mention

Controller

 $confernceIterationData = ConferenceIteration::with('AbstractNews')->withCount('AbstractNews')->where('id', $unserializeData['confid'])->first();
              
 $this->dispatch(new SendtronAutomatedEmailJob($confernceIterationData, $unserializeData, $attachments));

Controller Output of dd($confereceIterationData)

array:42 [
    "id" => 9085
    "conference_iteration_id" => "e3f65fda-7776-4e64-82d8-b5f1289141e2"
    "conference_id" => 259
    "name" => "American Association of Cancer Research Annual Meeting 2022"
    "acronym" => "AACR 2022"
    "abstract_news_count" => 8339
  ]

        $this->extractConfenceData($this->confrenceData);

      
 
        // dd($this->confrenceData->AbstractNews_count);

        $count = count($users);
        foreach ($users as $user) {
            Log::channel('sendtron_email')->info('Authomated Mail Send To .', ['id' => $user]);

            Mail::to($user)->send(new SendTronAutomatedMail($request['content'], $subject, $this->files));
            if (++$i === $count) {
                unset($users);
                TeamConferences::where('conference_iteration_id', $request['confid'])->whereIn('team_id', $request['teams'])->update(['last_mail_sent' => Carbon::now()->toDateTimeString()]);
                Storage::disk('s3SendTron')->delete(array_column($this->files, 's3path'));
            }
        }

    }
}

If we dd($confrenceData) in constructor we get the attribute abstract_news_count as mention in controller output.

but at the same time if we dd($this->confrenceData) we unable to get abstract_news_count
