    I had this issue on my project, it seems that the latest react-native 0.74 version introduced issues on the @react-native-community/cli-platform-android library.

    So you have to update your yarn.lock or package-lock.json file and search for the line react-native@*: then you have to remove all of dependencies and paste this code instead:

    react-native@*:
  version “0.73.6”
  resolved “https://registry.yarnpkg.com/react-native/-/react-native-0.73.6.tgz#ed4c675e205a34bd62c4ce8b9bd1ca5c85126d5b”
  integrity "your integrity sha512"
  dependencies:
    “@jest/create-cache-key-function” “^29.6.3"
    “@react-native-community/cli” “12.3.6"
    “@react-native-community/cli-platform-android” “12.3.6"
    “@react-native-community/cli-platform-ios” “12.3.6"
    “@react-native/assets-registry” “0.73.1"
    “@react-native/codegen” “0.73.3"
    “@react-native/community-cli-plugin” “0.73.17"
    “@react-native/gradle-plugin” “0.73.4"
    “@react-native/js-polyfills” “0.73.1"
    “@react-native/normalize-colors” “0.73.2"
    “@react-native/virtualized-lists” “0.73.4"
    abort-controller “^3.0.0”
    anser “^1.4.9"
    ansi-regex “^5.0.0”
    base64-js “^1.5.1"
    chalk “^4.0.0”
    deprecated-react-native-prop-types “^5.0.0"
    event-target-shim “^5.0.1”
    flow-enums-runtime “^0.0.6"
    invariant “^2.2.4”
    jest-environment-node “^29.6.3"
    jsc-android “^250231.0.0”
    memoize-one “^5.0.0"
    metro-runtime “^0.80.3”
    metro-source-map “^0.80.3"
    mkdirp “^0.5.1”
    nullthrows “^1.1.1"
    pretty-format “^26.5.2”
    promise “^8.3.0"
    react-devtools-core “^4.27.7”
    react-refresh “^0.14.0"
    react-shallow-renderer “^16.15.0”
    regenerator-runtime “^0.13.2"
    scheduler “0.24.0-canary-efb381bbf-20230505”
    stacktrace-parser “^0.1.10"
    whatwg-fetch “^3.0.0”
    ws “^6.2.2"
    yargs “^17.6.2”

    After that, remove your node-modules folder and install all again.

    Got same exception after upgrde to new version (0.74) of RN.

    In my case the problem was an old androidgradlew.bat
    It was created with previos RN version.

    I copied gradlew.bat from blank project, and this issue moved away.

    You may create reference project from last RN

    npx @react-native-community/cli@latest init TestProject

    P.S.
    There are a lot other diffirences in *.gradle files comes with new version of RN.
