[Bug] await page.solveRecaptchas() stopped working a couple of weeks ago with TimeoutError: Waiting failed: 10000ms exceeded

I was using puppeteer-extra-plugin-recaptcha with 2captcha for a several monthes, and some time ago it stopped working, I did not make any changes in project. Now I enabled logs and saw next:

On a screenshot I see cloudflare captcha

[LessThanGreaterThan]

so if i understand this correctly, you see on the page cloudflare turnstile, and are confused why recaptcha doesn't work ?

I assume you are using the rebrowser puppeteer runtime leak patches in alwaysIsolated mode.
Somewhere it reads that page.waitForFunction will not work in this case.
But node_modules/puppeteer-extra-plugin-recaptcha/dist/index.js is using page.waitForFunction as a convenience to wait for captchas to be fully loaded.
You can fix your problem by commenting out the waitForFunction block and make sure (by manually waiting a bit) that captchas are fully loaded.

   async findRecaptchas(page) {
        this.debug('findRecaptchas');
        // As this might be called very early while recaptcha is still loading
        // we add some extra waiting logic for developer convenience.
        const hasRecaptchaScriptTag = await page.$(`script[src*="/recaptcha/api.js"], script[src*="/recaptcha/enterprise.js"]`);
        this.debug('hasRecaptchaScriptTag', !!hasRecaptchaScriptTag);
        /*
        if (hasRecaptchaScriptTag) {
            this.debug('waitForRecaptchaClient - start', new Date());
            await page
                .waitForFunction(`
        (function() {
          return Object.keys((window.___grecaptcha_cfg || {}).clients || {}).length
        })()
      `, { polling: 200, timeout: 10 * 1000 })
                .catch(this.debug);
            this.debug('waitForRecaptchaClient - end', new Date()); // used as timer
        }
        */
        const hasHcaptchaScriptTag = await page.$(`script[src*="hcaptcha.com/1/api.js"]`);
        this.debug('hasHcaptchaScriptTag', !!hasHcaptchaScriptTag);
        /*
        if (hasHcaptchaScriptTag) {
            this.debug('wait:hasHcaptchaScriptTag - start', new Date());
            await page.waitForFunction(`
        (function() {
          return window.hcaptcha
        })()
      `, { polling: 200, timeout: 10 * 1000 });
            this.debug('wait:hasHcaptchaScriptTag - end', new Date()); // used as timer
        }
        */
        const onDebugBindingCalled = (message, data) => {
            this.contentScriptDebug(message, data);
        };
