Your complete test code (or attach your test files):

 import { Selector, ClientFunction } from 'testcafe';

fixture("Simple test")
        .page("https://devexpress.github.io/testcafe/example");

test('Zero Test', async t => {
	console.log(await t.eval(() => ({ w: window.outerWidth, h: window.outerHeight})))
	await t.expect(false).ok('this assertion will fail');
});
		

test('First Test', async t => {
    await t.setTestSpeed(1);
	
	debugger;
	
	console.log('testing console log');
	
    await t.typeText('#developer-name', 'Alex')
		.click('#submit-button');
		
		const { error } = await t.getBrowserConsoleMessages();

    await t.expect(error).eql([]);
});

	console.log('testing console log from the second test');
	
    await t.setTestSpeed(0.5);

It happens only if you specify singleFile: true (because there is no associated test for the video).
