in iOS SDK we are getting a freeze while presenting a survey from VC, Is there any solution to this?

Tech Stack
Platform: iOS Swift
Version: 4.21.0
Usage: SPM
We are using a V2 method as below:

func tracking(from vc: UIViewController?) {
    let eventPayload: EventPayload = .init(
      eventName: "someEventName",
      properties: someProps
    ) { [weak vc] state in
      guard let viewController = vc else { return }
      DispatchQueue.global(qos: .userInitiated).async {
        presentSurvey(from: viewController, state: state)
      }
    }
    
    UserLeapKit.Sprig.shared.track(payload: eventPayload)
}

private func myPresentSurvey(from vc: UIViewController, state: SurveyState) {
    guard case .ready = state else { return }
    DispatchQueue.main.async {
      UserLeapKit.Sprig.shared.presentSurvey(from: vc)
    }
  }

Please let us know if we are missing any usage instruction or there is some recent issue in the SDK itself
