QtCreator does not start (Windows 10)



  • I am using QtCreator 4.8.1 with Qt 5.12.1 on Windows 10 and it was working well till last week. But now whenever i start it using desktop icon or cmd nothing happens. In the Task Manager, the QtCreator service starts and then stops in a few seconds. I started the editor in gdb and the output is as given below:

    PS C:\Users\ADMIN> gdb E:\Qt\Tools\QtCreator\bin\qtcreator.exe
    GNU gdb (GDB) 7.8.1
    ...
    (gdb) r
    Starting program: E:\Qt\Tools\QtCreator\bin\qtcreator.exe

    Hi and welcome to devnet,

    @alamar213 said in QtCreator does not start (Windows 10):

    exited with code 030000000005

    This means you have a stack overflow. Are you creating anything really big on the stack ?



  • No I haven't created anything. This is the debug log from simply starting the editor.

    Can you try starting if with all plugins disabled ?
