@SrdjanTIs this a Windows application or a Web application (launched in Chrome or Edge)? If it is a Windows application, usually if the interrogation form closes immediately after the application starts, it means that the application you have set in the Path property is actually launching another application and then closing itself. In that case, you would use StartAndWait to launch the application in the Path property and wait for the application in the TargetPath property. You can also try to change the StartMethod to MonitorAll and set the Path property to the application. You would then start interrogation and when the interrogation form is up, launch your application manually. If you have any information about the application you can provide though, I might be able to assist you further. You can use a Tool like "Process Explorer" to help identify the actual processes your application is using and determine how exactly  to get it setup with Pega Robotics.
