How to make pod init work for my Xcode project? - ios

Question

I am trying to integrate Firebase to my Xcode project using Cocoapods.
I'm running macOS Monterey 12.6 with Xcode 14.
But when I get to the part where I have to create a Podfile inside my project using pod init I run into this
/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.11.3/lib/cocoapods/user_interface/error_report.rb:34:in `force_encoding': can't modify frozen String (FrozenError)

I have tried updating Ruby, tried installing Cocoapods through brew install Cocoapods , installed Command Line Tools, nothing is working so far. I keep running into this same error.
Any help is highly appreciated!
