Async @objc didPullToRefresh selector crashes app swift 5.5

I have a table to which I've added a refreshControl and when I pull down the table to refresh the data, I reset the array that feeds the table with data and then immediately request new data through an API call.

Until now, I have used completion handlers and protocols to get the data into the table view but I want to move the logic to async/await because of the complexity needed by the network calls and the pyramid of nested closures.

Populating the view in viewDidLoad works fine but with pullToRefresh selector I get an error:

Thread 1: EXC_BAD_ACCESS (code=1, address=0xbcf917df8160)

override func viewDidLoad() {
    super.viewDidLoad()
    setupView()
    setupTableView()
    setupTableRefreshControl()
    Task {
      await getBalances() //async network call
      myTable.reloadData()
    }
  } 

   func setupTableRefreshControl() {
    myTable.refreshControl = UIRefreshControl()
    myTable.refreshControl?.addTarget(self, action: #selector(didPullToRefresh), for: .valueChanged)
  }

Code that crashes app:

   @objc func didPullToRefresh() async {
    balance.reset() // reset array to []
    Task {
      await getBalances() //async network call
      myTable.reloadData()
    }
  }
