Chrome Automation Bot Debugging

I have an existing Chrome-based automation script that suddenly stopped behaving as expected. It is supposed to fill out forms, click buttons, and move smoothly from page to page, but it keep getting 403. Your task is to dig into the code, and get everything running flawlessly again.

You are welcome to work in the same language and framework already used—if you are comfortable with Python + Selenium, Playwright, or Puppeteer, that is ideal. I will give you:

• The current source and a short video showing the failure points
• Test credentials and URLs for each flow the bot must complete

Deliverables:
1. A corrected, fully functioning bot script.
2. A concise change log explaining what you fixed or refactored.
3. Quick setup/run instructions so I can verify on my end.

Once I confirm the bot fills forms, clicks the intended elements, and navigates every page without errors, we’re done. If you spot any opportunities to speed up execution or make the selectors more resilient, please note them as part of the changes.
