I keep on having to activate my Katalon Studio on startup

Hi,
I have recently upgraded to Katalon Studio v 6.2.1, and each time I start Katalon Studio, I am prompted with the Katalon Studio Activation popup.

I enter my email address and password, and proceed from there without issue.

Is there something I can do to prevent the Katalon Studio Activation popup from appearing each time I start Katalon Studio?

Thanks
Mark

I also have the same issue on my Macbook
