DAQmxCreateTask when called,the GUI hangs

Hello Guys,

I have created a UI which connects to a hardware. I have started writing code for the hardware connection in my UI source code which can be seen below. As soon as the code executes the DAQmx configure code: -DAQmxCreateTask("Dev0-R",&taskHandle[0]);, the UI hangs and does not work further. Can anyone tell me what exactly is the problem. I an not connected to any hardware currently but creating a task command should work in my case. I am confused how to go further. Please help.

// Code is shown below

TaskHandle    taskHandle[4];

int main (int argc, char *argv[])
{
    int error = 0;
    
    /* initialize and load resources */
    nullChk (InitCVIRTE (0, argv, 0));
    errChk (panelHandle = LoadPanel (0, "PintschBamag.uir", PANEL));
    errChk (AttributePanelHandle = LoadPanel (0, "PintschBamag.uir", ATTR_PANEL));
    
    /* display the panel and run the user interface */
    errChk (DisplayPanel (panelHandle));
    
    /* Place for configuring the Hardware Channel connection*/
    
    /*FOr the DAQMx*/
    //char        errBuff[2048]={'\0'};
    
    /*********************************************/
    // DAQmx Configure Code
    /*********************************************/
    DAQmxCreateTask("Dev0-R",&taskHandle[0]);
    DAQmxCreateTask("Dev3-R",&taskHandle[1]);
    DAQmxCreateTask("Dev4-R",&taskHandle[2]);
    DAQmxCreateTask("Dev5-R",&taskHandle[3]);

//code ends here

Thanks,
