Hi,  
While opening the Katalon Studio, I am receiving the below mentioned error and attached the log file for reference.

Please look into this and suggest to proceed further.

**Popup Error:**  
An error has occurred. See the log file.

Please delete folder: `D:\Katalon Studio_Windows_64-6.1.2\config\.metadata\.plugins\org.eclipse.core.resources` then reopen Katalon Studio again.

Thanks
