rspec tests won't after upgrading from rails 7.1.2 to 7.1.3.2: can't modify frozen Array when requiring environment file

Steps to reproduce

I'm trying to update rails from version7.1.3.2 to 7.1.2 along with it's dependencies.
The Gemfile is as follows:

source "https://rubygems.org"
git_source(:github) { |repo| "https://github.com/#{ repo }.git" }

ruby "3.2.2"

# Bundle edge Rails instead: gem "rails", github: "rails/rails", branch: "main"

gem "tzinfo-data", platforms: %i[mingw mswin x64_mingw jruby]

# Reduces boot times through caching; required in config/boot.rb
gem "bootsnap", require: false

# Use Sass to process CSS
# gem "sassc-rails"

# Use Active Storage variants [https://guides.rubyonrails.org/active_storage_overview.html#transforming-images]
# gem "image_processing", "~> 1.2"
gem "pg"

# Object geocoding (by street or IP address), reverse geocoding (coordinates to street address), distance queries for
# ActiveRecord and Mongoid, result caching, and more. Designed for Rails but works with Sinatra and other Rack
# frameworks too.
gem "geocoder", "~> 1.8", ">= 1.8.1"

# A ruby wrapper for ImageMagick or GraphicsMagick command line.
gem "mini_magick"

# RQRCode is a library for creating and rendering QR codes into various formats. It has a simple interface with all the
# standard QR code options. It was adapted from the Javascript library by Kazuhiko Arase.
gem "rqrcode", "~> 2.0"

group :development, :test do
  # See https://guides.rubyonrails.org/debugging_rails_applications.html#debugging-with-the-debug-gem
  gem "debug", platforms: %i[mri mingw x64_mingw]
  gem "pry"
  gem "pry-byebug"
  gem "rspec-rails", "~> 6.0.0"
  gem "rubocop", require: false
end

group :development do
  # Use console on exceptions pages [https://github.com/rails/web-console]
  gem "web-console"

  gem "better_errors"
  gem "binding_of_caller"

  # Add speed badges [https://github.com/MiniProfiler/rack-mini-profiler]
  # gem "rack-mini-profiler"

  # Speed up commands on slow machines / big apps [https://github.com/rails/spring]
  # gem "spring"
  # RBS is the language for type signatures for Ruby and standard library definitions.
  gem "rbs", "~> 3.0", ">= 3.0.4"
end

group :test do
  # Use system testing [https://guides.rubyonrails.org/testing.html#system-testing]
  gem "capybara"
  gem "selenium-webdriver", "~> 4.11"
end

To isolate the problem, I tried to do the following:

1. update only rspec-rails and check if all tests run correctly by running bundle update rspec-rails: all tests run correctly without errors

Expected behavior

• my tests should run normally

Actual behavior

• running rspec wiith or without arguments now return this error:

System configuration

Rails version: 7.1.3.2 upgraded to 7.1.2
OS: MacOS 14.4.1 on Apple Silicon (M1 chip)
-Bundler version: 2.4.10

Ruby version: 3.2.2

Anyone has an idea on what went wrong? As noted before, I tried updating only rspec-rails and all tests ran without issues, its the rails update that caused this error. I purposely only updated only rails to isolate the issue here.

You can clone rails locally, point your app to the local copy of rails via gem 'rails', path: '/my/path/to/rails' and try to run git bisect on the rails directory to identify which commit caused that behaviour.

7.1.3.2 upgraded to 7.1.2

I'm confused. Are you upgrading to 7.1.3.2? Because going from 7.1.3.2 to 7.1.2 is a downgrade, not an upgrade. 7.1.3.2 is a security release which means 7.1.2 is vulnerable to the security issues we fixed in 7.1.3.2.

No, I'm upgrading from 7.1.2 to 7.1.3.2.

Apparently it's linked to some routing modifications. Bisect gave me this commit: 0821d25
