Katalon Studio error Unable to open browser with url: ''

Question

I'm new to Katalon Studio and I want to do some simple web-tests. So I try to open browser, but always getting error Unable to open browser with url: '' It doesnt work with both chrome and firefox browsers. However when I try to run it in Web Recorder it works perfect with both browsers

I already tried to add

{“CHROME_DRIVER”:{“args”:["–no-sandbox","–disable-infobars"]}} 

as it was mentioned in threads with the same error

If someone help, I would be glad

WebUI.openBrowser("")
// some code
WebUI.closeBrowser()

Full error:
