CircleCI 2.0 iOS build stuck at Signing

Question

I am building my React Native iOS app with circleci 2.0, my build is stuck at Signing for about 40 minutes and not moving ahead. I have my apple id with 2FA so have added FASTLANE_APPLE_APPLICATION_SPECIFIC_PASSWORD in environment variables. My github id is also having 2FA and have deployed adhoc certificates on git with GH_TOKEN in circle ci env. variables.

My Fastlane file looks like this -

update_fastlane

default_platform(:ios)

platform :ios do
  before_all do
    setup_circle_ci
  end
  desc "Push a new beta build to TestFlight"
  lane :beta do
    increment_build_number(xcodeproj: "xxxApp.xcodeproj")
    match(type:'adhoc')
    gym(export_method: "ad-hoc")
    build_app(workspace: "xxxApp.xcworkspace", scheme: "xxxApp")
    # upload_to_testflight
  end
end

My circle ci config.yml looks like this

Output from CircleCI -

It doesn't move ahead and stuck at this for 40 mins
