I can’t see what upgrading the version will do except put you into a more “Pay for Features” KS application. If you are already a paying KS user, then you should put in a response to Katalon Technical Team instead of this forum.

How about instead of using the “openBrowser()” statement (with empty parameters), you try the other form of the statement?  
`WebUI.openBrowser("http://forum.katalon.com/")`
