I found some suggestions and I deleted cache, lib and bin folder but still I am getting this exception

Hi @kalpanabehera,
See this posting: Cannot open Katalon after latest update - #3 by duyluong

By the way I found this possible solution by searching the forum for: ‘org.eclipse.core.internal.dtree.ObjectNotFoundException: Tree element’

Please delete folder <Katalon_Studio_installed_folder>config\.metadata\.plugins\org.eclipse.core.resources then reopen Katalon Studio again.

Thanks.
