    I'm having the same problem.

    C:\Qt\Tools\QtCreator\bin\qtcreator -noload all
    

    produces an error:
    Failed to load core: Core plugin is disabled

    &

    C:\Qt\Tools\QtCreator\bin\qtcreator -noload all -load Core
    

    launches a greyed out very minimalistic unusable Qtcreator window.

    I've installed Qt 5.14 with QtCreator 4.11 (MinGW 7.3.0 32bit). Please, help.

    @jyotib When go through the plug-ins and always disable only one until QtCreator starts.
    Usually Welcome plug-in is the one causing problems.

          @jsulm Is it possible that i didn't installed some components and that resulted in this situation? I followed this youtube video link text during installation. And i'm using windows 10 64 bit system.

                  @jyotib When I guess it is another plug-in. As I suggested before: go through all plug-ins and disable one in each step and see whether QtCreator starts or not.

                      Do you mean it does not start?
                      Any anti-virus software running?
                      How did you install QtCreator and which version?

                        I realize this is an old thread, but in the chance someone else stumbles upon it this while beating their head trying to figure out WHY Qt Creator mysteriously won't start anymore, I wanted to share what worked for me. After scouring the internet for hours today when both Qt Creator and Qt Design Studio mysteriously wouldn't open anymore, I found QTBUG-50371. Apparently it's still a bug, because sure enough, when I disconnected my second monitor, they were magically able to start again.
