A dev would be better at answering this but I would say that whenever I have had 'unable to open browser with url “” ’ message, sometimes restarting machine or Katalon has fixed it. (Clean project first). If this doesn’t fix it, then the message on Katalon docs is: " **ignoreProtectedModeSettings** determines whether to skip the protected mode check. If set, tests may become flaky or unresponsive, and browsers may hang. If not set, and protected mode settings are not the same for all zones, an exception will be thrown on driver construction. Only “best effort” support is provided when using this capability." > **[Desired Capabilities](https://docs.katalon.com/katalon-studio/docs/introduction-to-desired-capabilities.html#internet-explorer)** > > Desired Capabilities are key/value pairs that tell the browser properties such as browser name, browser version, and the path of the browser driver in the system to determine the browsers'... Best of luck, Dan ---
