These are the exceptions that the underlying code or APIs are throwing to the calling code. Using Try Catch block you can catch specific exceptions and display custom messages to the end users, You can use the system generated messages as part of the stack trace for further debugging purpose.

If you don't want to display any messages, then you swallow all exceptions in the catch block. But this is not a good practice.

Do you mean you are blocking the application through your application and then when you start any of these blocked applications, you are getting this message?

I don't think you can block or modify the messages that OS is generating unless you are calling them through your code. In your case you have informed the OS that a particular app is blocked. Now when OS is starting this app, it recognizes that app is blocked and it is throwing an error.
