[New API] Invalid owner of PluginTask

My code is:
$par["room"] = $room;
$par["num"] = 0;
$this->getServer()->getScheduler()->scheduleDelayedTask(new TimerOut($par), 20);

But the server crashed, showed an error: "Invalid owner of PluginTask"
What is the matter, how can I fix it ?? I need help !

but how can i transfer parameters ?

But i don't want to transfer the main class. i only want to transfer the $par. and it may run a few times in one second.

What do you mean?

Can you upload all files?

Every task, must have an owner, or it will become a DeadLock or whatever it called, so you must pass it's owner

Code:

$this->getServer()->getScheduler()->scheduleDelayedTask(new TimerOut($this, $par), 20);

and in the TimerOut class

Code:

class TimerOut extends PluginTask{

    private $plugin;
    private $par;
   
    public function __construct(Plugin $plugin, $par){
        parent::__construct($plugin);
        $this->plugin = $plugin;
        $this->par = $par;
    }
