I have dowloaded from the website the katalon studio IDE in Ubuntu 18.04LTS MATE edition. After downloading the `Katalon_Studio_Linux_64-6.1.5.tar.gz` and exsdtracting via this command:

`tar -xvf Katalon_Studio_Linux_64-6.1.5.tar.gz` afterwards I launch it via the following command sequence:

```auto
cd Katalon_Studio_Linux_64-6.1.5
./katalon

```

It shows the Greeder for Katalon IDE but then for an unexpected reason I have not any other window oppened or anything to indicate me that Katalon Studio works. Also I have no idea where any application logs exist.

I would appreciate if any help for that.
