    I am facing the same issue and still unable to get any solution. I’ve tried

    • removing and re-installing pod
    • changing the minimum deployment version to 13.0

    but the issue still exists.

    we faced same error message, and we find out that

    echo $REACT_NATIVE_PATH

    outputs into empty string.
    You may check React-Fabric in PODS (via XCode) and you can see Build Phase named [CP-User] [RN]Check rncore where IF condition is blocking you:

    if [[ ! -d "$rncorePath" ]]; then
  echo 'error: Codegen did not run properly in your project. Please reinstall cocoapods with `bundle exec pod install`.'
  exit 1
fi

    Then we ran:

    export REACT_NATIVE_PATH=<absolut_path_to_proj>/node_modules/react-native

    And everything starts to run 🙂
