Jest-electron-runner hangs on simple test

When using jest-electron-runner on a simple test: it starts running the test, launches electron process and then hangs without making a progress.

Removing jest-electron-runner makes the test run without issues.

Jest config:

module.exports = {
    "transform": {
        "^.+\\.tsx?$": "ts-jest"
    },
    "globals": {
        "ts-jest": {
            "tsConfig": "./tsconfig.json"
        }
    },
    "moduleFileExtensions": [
        "ts",
        "tsx",
        "js",
        "json",
        "node"
    ],
    "runner": "@jest-runner/electron/main",
    "testEnvironment": "node",
    "testMatch": ["**/test/**/*.(spec|test).ts"]
};

Test file:

describe("calculate", () => {
  it("add", () => {
    const result = 5 + 2;
    expect(result).toBe(7);
  });
});
