Timeout when launching a Desktop Application Testing

On Oct 10, 2019, the Microsoft team had published a pre-release version (WinAppDriver v1.2 4), which includes a new capability ms:waitForAppLaunch 4. With this capability, you will be able to wait longer for your app to open.

You will also need to install Appium version 1.16.0 or later 4 for supporting WinAppDriver 1.2 4.

To use ms:waitForAppLaunch capability in Katalon, you could add Project Settings to the Desired Capabilities section.
