It was working fine 12 hours ago, but something has gone wrong

Hello,
Everything was working perfectly just 12 hours ago on window, but now several unexpected issues are occurring:

1. self.driver.get_log("performance") return []
2. While debugging with headless=False, the Chrome window automatically closes the moment I open the Chrome Developer Tools.
3. When several tabs are open, opening a new tab and navigating to a page causes the focus to switch back to a previous tab.

The website's source code has not changed.
Is this issue happening only to me?

1. Both examples/raw_performance_logs.py and examples/raw_cdp_logging.py are working normally for me.
2. Websites can detect when Devtools is open, and they can make your browser close when that happens.
3. I'm not seeing any unusual behavior with multiple tabs. Try examples/cdp_mode/raw_tab_switching.py.
