Issues are with browser preferences, try to switch the system to English till the issue is resolved.

anyone who is going to take over a task needs to add one of these args (found best fitted for it)

@gpBlockchain thank you for your question. To change the language you have to provide an accept-lang argument to puppeteer and playwright options during the initial bootstrap method call:

await dappeteer.bootstrap({
      .... // other parameters,
      playwrightOptions: {
        args: ["--accept-lang=en"],
      },
      puppeteerOptions: {
        args: ["--accept-lang=en"],
      },
    });
