Hi, I would like to ask if anyone has encountered an ntdll.dll error/crash? I already created an installer for my Qt project and made the installer using inno setup. When I install and run the program, it goes well but it only crashes when I press the 'x' or exit button found at the upper right hand corner of the software.

I double checked my code and found out that upon close event, the destructor for my widget is called. I already commented this out, created another installer and run it but it still crashes.

what is ntdll.dll for?

thanks!
