resolved, is not a but but Katalon require all zones (Internet, Local intranet, Trusted sites, Restricted sites) have to the same protected mode (enable or disable)

1. Open IE
2. Go to Tools -\> Internet Options -\> Security
3. Set all zones (Internet, Local intranet, Trusted sites, Restricted sites) to the same protected mode, enabled or disabled

NB: set also zoom to 100%
