Hello,  
Please help me…  
My test suite collection execution is keep continuing with 0% execution status. Getting lots of ‘Unable to resolve class errors’ and several below exceptions. Why Katalon is using “ch.qos.logback.classic”?  
I have attached my yml file screenshot.

@rismat  
Please temporarily remove “–config -webui.autoUpdateDrivers=true” parameters and run again. We will release a hot-fix soon.

Hi @anuradha, It did not resolve my issue.  
@duyluong, I’m still getting error. Looks like my url is not launching in the browser hence it is giving WebElement not found error. See the error details below (I’m using Katalon 7.7.0). Please tell us what to do next.
