CircleCI 2.0 iOS build stuck at Signing

Hi All,
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”)
end
end

My circle ci config.yml file looks like this -
