Katalon can't open Safari Browser on Mac


I installed Katalon Studio 8.5.3.alpha on my MacBook (Ventura 13.1) and want to execute tests with Safari.

I get the following error:

=============== ROOT CAUSE =====================

Caused by: org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:29315

I already tried the steps described here: How do you enable/allow safari browser to run test

but it’s still not working.
