My KS is not running tests within test suite

I’m using Katalon Studio where my test suite runs(before and after test suite) but none of the tests within test suite run and no errors are shown. If it is a license issue then how do I can extend it?

It is not be a license issue at all.
Katalon Studio Free plan should work for you.
