flutter runができない (iOSのビルドができなくなった)

今まで、VS codeとiOs simulatorを使用しflutterで問題なくコーディングできていたのですが、最近急にiOSがbuildしなくなりました。stackoverflowなどを調べていくつか試したのですが、全く立ち上がらなくなり、恥ずかしながら泥沼にハマってしまいました。

terminalでのErrorは下記のように出ます。

Launching lib/main.dart on iPhone 13 in debug mode...

ここのサイトを参照しましたが、Xcode上でうまくいかない（どうすれば良いかわからない）です。

解決方法をお教えしていただきたいです。よろしくお願いします。
