Need Help with Task

I have a plugin with a Task but I wont work I dont know why?

Code:

[00:22:01] [Server thread/CRITICAL]: Error: "Cannot call constructor" (EXCEPTION) in "/phar_Core_wVkNyrAXoG6Sn2K.phar/src/StuckDexter/Core" at line 2988
[00:22:01] [Server thread/INFO]: Disabling Core v2
[00:22:01] [Server thread/INFO]: [Core] Config saved

Thats the code

PHP:

class Chest extends PluginBase{

    public function __construct(Core $plugin) {
        parent::__construct($plugin);
        $this->plugin = $plugin;
    }
  
public function onRun($tick){
            $chests = new Config($this->plugin->getDataFolder() . "chests.yml", Config::YAML);
                $level->addParticle(new FloatingTextParticle(new Vector3($chests->get("XChest1"), $chests->get("YChest1"),$chests->get("ZChest1")),"",  "§l§6<==CHEST==>
                §a-->>>OPEN<<<--"));
}
}

 

A task is supposed to extend PluginTask, not PluginBase.

 

Oh Im so stupid
