For the love of God why IOS app crash on start when add ADs?

I'm trying to add AD to my project using ADmob and UnityAds.
I'm gonna explain every step to be more clear.

Added and import plugins to the editor, enable the service, configure on both sides(editor / admob site) - no problems were there.
Build shows succeed, .unityproject opened, configured general settings and press "Archive"
Archive failded.
Error: ‘GoogleMobileAds/GoogleMobileAds.h’ file not found and build crashed

I googled. Fixed with:
Play Services Resolver -> IOS Resolver -> Install cocoapods
Via terminal install cocoapods and run "pod install"
.workspace file was created, opened and Archive

Archive failed.
error: linked command failed with exit code 1" (Screenshot 1)

ld: 3 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)



I googled.
Found this solution and it was unchecking the unity-iphone project at "Target Membership" in UnityAdsUnityWrapper.mm file

Archive succeed, uploading to the TestFlight successful.
Run the app. Shows black screen and immediately crashes(close).

I googled.

Set back the flag at target membership and disable built-in Ads extension in Unity Editor Services. Build and archive. All successful but same result. Crash on initialization.

So i still don't know how to fix it.
Thanks to everyone who is not indifferent
