Jest cannot find test files anymore

I have multiple project with the same jest configuration.

In those projects, everything was working properly before the installation of some packages this morning.

I installed Android Studio, watchman react-native, autoconf ...

I tried with node 12 and node 14 but without success.

I am getting following errror:

No tests found, exiting with code 1
Run with `--passWithNoTests` to exit with code 0
No files found in /home/bastio/projects/heyliot/back/function-app-iot-gateway/app.
Make sure Jest's configuration does not exclude this directory.
To set up Jest, make sure a package.json file exists.

jest.config.js

module.exports = {
    testPathIgnorePatterns: ["<rootDir>/node_modules/", "<rootDir>/__tests__/?.*/utils/.*", "<rootDir>/__tests__/dataset", "<rootDir>/tests/.*"],
    testMatch: ['<rootDir>/__tests__/**/*.test.js'],
    roots: [],
    setupFiles: ["./__tests__/utils/setEnvVars.js"],
    verbose: true
}

UPDATE: With or without the testMatch I have the same result.
