解決したいこと
1. HomeHeaderViewCellに設置したaccountButtonをタップしてMyAccountViewCotrollerへ遷移させたいのですが、アプリが落ちてしまいます。遷移の処理はHomeViewControllerにデリゲートしています。理由がわからないので教えてほしいです。アプリが落ちた時のデバッグを貼っておきます。コードは長すぎて見辛くなるので、Gitからご覧いただけると幸いです。

2. accountButtonのレイアウトをlayoutSubviews()内に書いたのですが、角丸と画像の設定だけ反映されません。このメソッドを使うのが良くない気はしたのですが、headerLabelのレイアウトやaccountButtonの backgroundColor は反映されているので理由がわかりません。分かる方がいらっしゃいましたらご教授ください。
override func layoutSubviews() {
self.backgroundColor = .clear
headerLabel.text = "Home"
headerLabel.font = UIFont.boldSystemFont(ofSize: 40)
headerLabel.backgroundColor = .clear
headerLabel.textAlignment = .left
accountButton.layer.cornerRadius = accountButton.frame.height / 2 //これ
accountButton.layer.masksToBounds = true
accountButton.backgroundColor = .cyan
accountButton.imageView?.contentMode = .scaleAspectFit
accountButton.imageView?.image = UIImage(systemName: "person.fill") //これ
}
