Solved Tile stays for 1 sec and removes

Code

PHP:

   $chest = Tile::createTile("Chest", $sender->getLevel(), new CompoundTag("", [ new StringTag("id", "Tile::Chest"), new IntTag("x", floor($sender->x)), new IntTag("y", floor($sender->y)), new IntTag("z", floor($sender->x))]));

        $block = Block::get(Block::CHEST);
        $block->x = $chest->x;
        $block->y = $chest->y;
        $block->z = $chest->z;
        $block->level = $chest->getLevel();
        $block->level->sendBlocks([$sender], [$block]);

       foreach($player->getInventory()->getContents() as $item) {
       $chest->getInventory()->addItem($item);
       $sender->addWindow($chest->getInventory());


Basically when I execute command I see the inventory for a split second then it randomly disappears
