Katalon studio is not working

Today my katalon studio is not working and just show a logo
my os version : ubunto 18.0.4

You could provide some more info about your Problem, like wich version you’re using for example…

Maybe read this post beforehand:

@arefmws have you recently did any changes to your system?
e.g upgraded OS? or re-installed/upgraded Katalon?
I doubt an application stopped working just because New Year is coming … usually there is a reason

i delete katalon studio and install another version , Thanks all
