Qt Creator error: Cannot retrieve debugging output

Qt Creator allows you to open and run multiple instances of Qt Creator at the same time. But there is a small glitch. If you are running multiple instances of Qt Creator, only the first instance displays the console output in the Application output console. The second instance would complain with the following error message:

Cannot retrieve debugging output

Fix for this is to close the second instance or open the project you want to edit and debug in the first instance.
