Puppeteer Crawler cannot open the page

Hi,
I have a puppeteer scrapper, which worked just fine until this Monday. Nothing is changed, but scrapper stopped working.

The HTML markup of the page is not changed, a[data-testid="search-listing-title"] this element is still there. Apify run logs says it is failing to find this HTML element:

TimeoutError: waiting for selector a[data-testid="search-listing-title"] failed: timeout 30000ms exceeded

TimeoutError: waiting for selector a[data-testid="search-listing-title"] failed: timeout 30000ms exceeded

I have tried to launch scrapper from local machine and it did work but does not work on Apify platform. I guess something has to do with proxy.
This is part of my code:

//...
const proxyConfiguration = await Apify.createProxyConfiguration();

const launchContext = {
  useChrome: true,
  stealth: true,
  launchOptions: {
    headless: true,
  },
};

const crawler = new Apify.PuppeteerCrawler({
  requestList,
  requestQueue,
  proxyConfiguration,
  launchContext: launchContext as any,
  maxRequestRetries: 5,
  handlePageTimeoutSecs: 180,
  navigationTimeoutSecs: 180,
  async handlePageFunction({ page, request }): Promise<void> {

  await utils.puppeteer.saveSnapshot(page, { key: 'beforescrap', saveHtml: false });
  const cheerio = load(await page.content());

  const html = cheerio.html();
  await Apify.setValue('htmlstring', html, { contentType: 'text/html' });

  await page.waitForSelector('a[data-testid="search-listing-title"]');
//...

//...
const proxyConfiguration = await Apify.createProxyConfiguration();

const launchContext = {
  useChrome: true,
  stealth: true,
  launchOptions: {
    headless: true,
  },
};

const crawler = new Apify.PuppeteerCrawler({
  requestList,
  requestQueue,
  proxyConfiguration,
  launchContext: launchContext as any,
  maxRequestRetries: 5,
  handlePageTimeoutSecs: 180,
  navigationTimeoutSecs: 180,
  async handlePageFunction({ page, request }): Promise<void> {

  await utils.puppeteer.saveSnapshot(page, { key: 'beforescrap', saveHtml: false });
  const cheerio = load(await page.content());

  const html = cheerio.html();
  await Apify.setValue('htmlstring', html, { contentType: 'text/html' });

  await page.waitForSelector('a[data-testid="search-listing-title"]');
//...

I have tried to take a screenshot to see what the page looks like and it gives blank white page.
I have also tried to change proxy settings to use residential servers and change the country - also did not work.
How can I debug this?
Logs screenshot is also attached.
