vision-camera-code-scanner Undefined symbols for architecture x86_64 react native

I am getting a build error when using the vision-camera-code-scanner package for my react native project.

The short hand error is:

Undefined symbols for architecture x86_64

The full error is the following:

ld: warning: ignoring file /XXXXXXXXXXXXXXXXXXX/Build/Products/Debug-iphonesimulator/vision-camera-code-scanner/libvision-camera-code-scanner.a, building for iOS Simulator-x86_64 but attempting to link with file built for iOS Simulator-arm64

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have tried to fix the issue by running: pod deintegrate && pod cache clean --all and then pod install in the ios directory as per the following similar question.

Sadly this didnt fix the issue i also tried the steps suggested in the following thread: namely excluding the target arm64. But this also didnt fix the error.

I also read the following on this github thread:

It’s related to the fact that Google MLKit Team does not ship ARM simulator binaries and we can’t compile ourselves because the source code is not public

So now i am a bit lost what to do.
Any help or suggestions greatly appreciated.

Working on mac book pro M1 14 inch
running latest version of react native

If additional information is needed please let me know so i can add it to the question.

    As per my findings on this topic, Google MLKit does not support arm64 yet (found it when trying an option to import it through SPM on an iOS project). The only way to build this on an M1 machine is to run the entire project on x86_64 compatiblity using Rosetta 2. However, running Xcode in compatibility mode is not a supported configuration by Apple, so there could be other errors with this choice.

    You have to exclude arm64 from your pod file by following these steps:

    1. Add this to your pod file:
    post_install do |installer|
  react_native_post_install(installer)
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
  end
end
    1. Make sure to use this flipper version in your pod file:
    use_flipper!({'Flipper' => '0.79.0'})
    1. Then, clean your pods and reinstalled them:
    rm -rf ~/Library/Caches/CocoaPods && rm -rf ./ios/Pods && rm -rf ~/Library/Developer/Xcode/DerivedData/* && pod deintegrate && pod setup && npx pod-install
