Undefined symbols for architecture arm64

[francoangulo]

So like the title of this issue says, I'm getting Undefined symbols for architecture arm64 error for several RNGestureHandler elements.
This happens as soon as I enable the new architecture in my project, and goes away as soon as I disable it.
The thing is that react-native v0.82 is already out and they are not giving support for old architecture anymore, so my team needs to make it work.
I got this to work by adding a post_install script in my Podfile, but I'm not sure how stable and reliable it is.
This is something like a discussion asking if anyone has experienced this before and knows or have a better resolution that can be considered as stable and reliable.

Showing All Errors Only
Undefined symbol: facebook::react::RNGestureHandlerButtonProps::RNGestureHandlerButtonProps(facebook::react::PropsParserContext const&, facebook::react::RNGestureHandlerButtonProps const&, facebook::react::RawProps const&)

Undefined symbol: facebook::react::RNGestureHandlerButtonComponentName

Linker command failed with exit code 1 (use -v to see invocation)

Maybe attaching here my post_install script someone could get some hints on what is going on:

    def add_fabric_components(installer, target_name, component_path)
      target = installer.pods_project.targets.find { |t| t.name == target_name }
      return unless target

      fabric_files = ['Props.cpp', 'ShadowNodes.cpp', 'ComponentDescriptors.cpp', 'EventEmitters.cpp', 'States.cpp']
      
      fabric_files.each do |file_name|
        file_path = File.join(installer.sandbox.root, "../build/generated/ios/react/renderer/components/#{component_path}/#{file_name}")
        if File.exist?(file_path)
          file_ref = installer.pods_project.new_file(file_path)
          target.source_build_phase.add_file_reference(file_ref)
          puts "✅ Added #{file_name} to #{target_name}"
        else
          puts "⚠️  #{target_name} #{file_name} not found yet (will be generated during build)"
        end
      end
    end

    add_fabric_components(installer, 'RNGestureHandler', 'rngesturehandler_codegen')

I couldn't think of a better place to ask someone to get better understanding on what's going on

Steps to reproduce

react-native v0.81.4
react-native-gesture-handler v2.28.0

1- have the project running normally
2- enable new architecture by setting ENV['RCT_NEW_ARCH_ENABLED'] = '1' on Podfile
3- cd ios && pod install
4- run the app, it throws the error shown above
