Sorry, I don't know. I notice that you are not providing an Action for the app you are trying to start (or determine if it is not present). You might have to provide an appropriate Action.

Also it might be better to test initially by placing the call ActiviyStarter2.StartActivity in a Button (calling CloudDB2.lGetValue might be interfering) instead of in Screen.Initialize.

The instructions in the ActivityStarter link are certainly confusing. Only you can test this unfortunately.

Typical Action calls are summarized in ActivityStarter

What android do you use?
From my own experience I know that my app was unable to access other apps when app inventor was targeted at api level 30. Users of my app who use android 11 reported me an error. I had to add an permission on QUERY_ALL_PACKAGES to the manifest.

Writes that access is denied QUERY_ALL_PACKAGES. What to do?

You will need an extension to add this permission to the manifest. Add this extension to your project. You don't need to add a block that asks for permission.
