Is Katalon Studio unable to open the latest version of Chrome?

You can check the status of “Chrome for Testing” browser for automated testing at

What is “Chrome for Testing”? How is it similar to / different from Chrome? Read this:
Chrome for Testing: הורדות אמינות לאוטומציה של הדפדפן  |  Blog  |  Chrome for Developers

This page tells that the v121.0.6167.160 of “Chrome for Testing” is NOT ready. I have no idea what’s wrong in it. All we should do is to refrain from the version.

So, the cause of the problem possiblly resides in the latest version of Chrome, not in Katalon Studio. If you have got any problem, you should downgrade your Chrome installation and configure it so that it does not auto-upgrade.

It would be a good idea to use “Chrome for Testing” as I did before. Chrome for Testing v121.0.6167.85 would work OK and won’t auto-upgrade at all.
