hey @m1duza, could you please try applying this diff to statusPageMiddleware.js file?

szymonrybczak please help me, I don't understand where to insert this diff, and I'm sorry that I didn't notice what you wrote

@m1duza to check if the diff is working you can achieve it by replacing content of node_modules/@react-native-community/cli-server-api/build/statusPageMiddleware.js file to contain this code:

"use strict";

Object.defineProperty(exports, "__esModule", {
  value: true
});
exports.default = statusPageMiddleware;
function _path() {
  const data = _interopRequireDefault(require("path"));
  _path = function () {
    return data;
  };
  return data;
}
function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }
/**
 * Copyright (c) Facebook, Inc. and its affiliates.
 *
 * This source code is licensed under the MIT license found in the
 * LICENSE file in the root directory of this source tree.
 */

/**
 * Status page so that anyone who needs to can verify that the packager is
 * running on 8081 and not another program / service.
 */
function statusPageMiddleware(_req, res) {
  const projectRoot = _path().default.normalize(process.cwd());
  res.setHeader('X-React-Native-Project-Root', projectRoot);
  res.end('packager-status:running');
}

and then you need to start the dev server again with npx react-native start
