React native projects not running in IOS

Question

This is my error coming when I'm running the project in IOS 15 devices. It's not installing pod(pod install), I tried too many things but still I can't get any solution.

There is chance to have incompatibility issues with the ruby version.

Check the versions of the Ruby gem file, cocoapods, bundler, and update if needed.
