Client crashs when a chest is closed by a plugin

[Wertzui123]

Sourcode:

$ui = InvMenu::create(InvMenu::TYPE_CHEST);
$ui->setListener(function (Player $player, Item $clickedOn, Item $clickedWith, SlotChangeAction $action) {
    $player->removeWindow($action->getInventory());
});
$ui->send($player);

Expected result: An inventory which closes when you move an item into it.

Actual result: When you move an item into the inventory, it closes, the client starts freezing and crashes after a few seconds.
