Cannot build and archive iOS app but can run on simulator and device

Help General
1

I have been working on a flutter app for the past 2 years and I never (barely) updated the packages unless it was forced. Recently App Store has stopped supporting many libraries because it lacked privacy.plist file so it kinda forced me to upgrade my flutter to the latest (3.29.0). This also forced me to update many packages from pub.dev.

Ever since I updated my flutter and pubs, I have not been able to archive my build to app store. I can successfully run the app on simulator.

Here is the error I am getting. If anyone can help me out with this it would be greatly appreciated.

P.S I have no problems running and building android app

Perhaps this could help (run from your project folder):

pushd ios
rm -rf Pods Podfile.lock
pod install --repo-update
popd

This will essentialy rebuild the Pods references and reinstall them.
