Сборка Flutter iOS завершилась неудачно после обновления Flutter 1.22

Я только что обновил свою версию Flutter до 1.22.0. После обновления и внесения некоторых изменений в Firebase мое приложение для Android начало работать, но я не могу создать и запустить приложение iOS на эмуляторе или на физическом устройстве.

Терминал показывает следующие ошибки, когда я пытаюсь запустить приложение в эмуляторе или на физическом устройстве. Эмулятор работает на iOS 14, а физическое устройство - на 14.0.1.

Emulator: ld: symbol(s) not found for architecture x86_64
Actual device: ld: symbol(s) not found for architecture arm64

Я также выполнил следующие команды, но все еще не работал ...

flutter clean && \
rm ios/Podfile ios/Podfile.lock pubspec.lock && \
rm -rf ios/Pods ios/Runner.xcworkspace && \ 
flutter run

Похоже, эта проблема возникает из-за API RevenueCat. Когда я закомментирую импорт Purchases_flutter в файле pubspec.yaml, я могу установить приложение, но оно вылетает при запуске, говоря, что соединение потеряно.
