升级Xcode 15后iOS 17以下设备出现EXC_BAD_ACCESS错误求助

升级Xcode至15.0版本后，在iOS 17以下版本的设备（如iOS 16.4）上运行Flutter应用时，触发以下错误：

Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)

错误发生在PathMonitorConnectivityProvider.swift文件中，相关代码如下：

import Foundation
import Network

@available(iOS 12, *)
public class PathMonitorConnectivityProvider: NSObject, ConnectivityProvider {

  private let queue = DispatchQueue.global(qos: .background)

  private var _pathMonitor: NWPathMonitor?

  public var currentConnectivityType: ConnectivityType {
    let path = ensurePathMonitor().currentPath
    // .satisfied means that the network is available
    if path.status == .satisfied {
      if path.usesInterfaceType(.wifi) {
        return .wifi
      } else if path.usesInterfaceType(.cellular) {
        return .cellular
      } else if path.usesInterfaceType(.wiredEthernet) {
        // .wiredEthernet is available in simulator
        // but for consistency it is probably correct to report .wifi
        return .wifi
      } else if path.usesInterfaceType(.other) {
        return .other
      }
    }
    return .none
  }

  public var connectivityUpdateHandler: ConnectivityUpdateHandler?

  override init() {
    super.init()
    _ = ensurePathMonitor()
  }

  public func start() {
    _ = ensurePathMonitor()
  }

  public func stop() {
    _pathMonitor?.cancel()
    _pathMonitor = nil
  }

  @discardableResult
  private func ensurePathMonitor() -> NWPathMonitor {
    if (_pathMonitor == nil) {
      let pathMonitor = NWPathMonitor()
      pathMonitor.start(queue: queue)
      pathMonitor.pathUpdateHandler = pathUpdateHandler
      _pathMonitor = pathMonitor
    }
    return _pathMonitor!
  }

  private func pathUpdateHandler(path: NWPath) {
    connectivityUpdateHandler?(currentConnectivityType)
  }
}

错误截图显示错误指向上述文件中的相关代码逻辑。

AppDelegate.swift代码：

import UIKit
import Flutter
import GoogleMaps

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GMSServices.provideAPIKey("AIzaSyB0SHZK3ngwOu0r26fm3pOrhKumXS7XdHY")
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

该错误仅在iOS 17以下版本的设备上出现，寻求技术解决方案。
