Can you delete this 0.snap file and try again? Its location is: \<Katalon\_Studio\_installed\_folder\>\config.metadata.plugins\org.eclipse.core.resources\0.snap

if you are using an updated katalon version then your katalon installation location will be  
C:\Users\your system profile.katalon\packages
