I encountered the same error when trying to upgrade to the latest Google Mobile Ads SDK. I also attempted to downgrade some libraries based on recommended solutions, but that didn't work for me.

Eventually, I found that upgrading Xcode from 15.4.0 to 16.2.0 (the latest version) resolved the issue, and the build succeeded.
