Tried by both options, none helped .. still getting same error from "flutter doctor"

Option 1:

1. url -L https://get.rvm.io | bash -s stable

2. rvm install ruby-3.4.2

3. rvm use ruby-3.4.2

4. rvm --default use 3.4.2

5. sudo gem install cocoapods

Option 2:

1. rvm uninstall ruby-3.4.2

2. /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

3. brew install ruby 

4. updated .zshrc, to point PATH to /opt/homebrew/opt/ruby/bin

5. source ~/.zshrc

6. brew install cocoapods

In both options, validated that ruby version is 3.4.2 by running "ruby -v" command.

Getting same error and not able to overcome this error. Have been working to overcome it since two days. Any help would be appreciated.
