Qt Creator Freezes constantly

Qt Creator freezes constantly!

Whenever I execute Qt Creator, it freezes for more than 5 seconds indicating "Feching license". This is not related to my internet connection. It's 15Mbps.

If I create a simple qmake project using Qt Quick Controls 2 and material, Qt Creator freezes constantly for minutes in several situations. It's not always, but usually it freezes when I'm executing this simple app, and I make some changes into the qml while the app is running. Please note that I'm not debugging the app, although it's compiled in debug mode. 

It freezes more frequently if you are modifying a ui.qml file under Qt Quick Designer, but it also freezes while editing a regular .qml file. 

This is quite annoying and I couldn't find a pattern to send attached. Sometimes, If I have the app running and I simply add a new Qt Quick UI file, it freezes. Sometime it doesn't. 

The only pattern I found is that the app has to be running while you attempt to edit inside Qt Creator.

Everyday I have to open Windows Task Manager about 3 or more times to kill Qt Creator. The problem is that even to kill Qt Creator is quite difficult. It almost freezes the entire Windows. It takes a while to open Windows Task Manager. 

This problem is not restricted to version Qt Creator 4.4.1. Older versions had the same problem, and It also happens if I compile the app using MSVC2017 instead of MinGW5.3.
