Playwright showing strange behaviour: not respecting TimeOut values and GUI run is different...

I am testing my Angular 19 project using Playwright. I have built a game in angular and need a very long test run, maybe something like 15 minutes. Whatever I try, the run stops after 60.000ms (1 minute) with a timeout error. I run my tests using the --ui option:

npx playwright test --ui --config=playwright.config.js



Here is my config:

// @ts-check
const {defineConfig, devices} = require('@playwright/test');

console.log(`Setting up the environment`);

/**
* Read environment variables from file.
* https://github.com/motdotla/dotenv
*/
// require('dotenv').config({ path: path.resolve(__dirname, '.env') });

/**
* @see https://playwright.dev/docs/test-configuration
*/
module.exports = defineConfig({
timeout: 25 * 60 * 1000,
globalTimeout: 30 * 60 * 1000,
expect: {
timeout: 3 * 60 * 1000,
},
testDir: './tests',
fullyParallel: false,
forbidOnly: !!process.env.CI,
retries: process.env.CI ? 2 : 0,
workers: 1,
reporter: 'html',
use: {

locale: 'nl-NL',
actionTimeout: 10 * 60 * 1000,
trace: 'on-first-retry',
launchOptions: {
firefoxUserPrefs: {
'media.autoplay.default': 2 // 2 = block all autoplay
}
}
},

/* Configure projects for major browsers */
projects: [
{
name: 'firefox',
locale: 'nl-NL',
use: {...devices['Desktop Firefox']},
/*dependencies: ['setup']*/
},

],

});

console.log(`Setting up the environment done`);



And my test file:

test('Play Interventions - create named intervention and play', async ({page, context}) => {
test.setTimeout(15 * 60 * 1000);
page.setDefaultTimeout(5 * 60 * 1000)

....


And no matter the setup / config or calls to test.setTimeout(), the tests always ends after 60 seconds.

So I thought maybe to try it using the (Jetbrains) IDE runner. Then, the test will not find the right aria role/label and stops early. Now I have i18n implemented in Angular, but the default is dutch (NL) for Development mode. I run my Angular project with ng serve. I added a config option in the Playwright setup to set the locale (locale: 'nl-NL',) but that doesn't help either.

Any help would be greatly appreciated.

So I'm stuck... I've read quite a lot, looked at the Playwright website
