Xcode – iOS Framework addition failed due to a Cocoapods installation failure

when i try to build my unity project for IOS, Unity creates an error related with Firebase and Cocoapods. I could not find any solution. Can you please advice me to solve the error.
Thanks

Unity Console Error Message;

iOS framework addition failed due to a CocoaPods installation failure. This will will likely result in an non-functional Xcode project.

After the failure, "pod repo update" was executed and succeeded. "pod install" was then attempted again, and still failed. This may be due to a broken CocoaPods installation. See: https://guides.cocoapods.org/using/troubleshooting.html for potential solutions.

pod install output:

versions for pod "GoogleAppMeasurement": In Podfile:

on GoogleAppMeasurement (~> 7.0)
