HardFault_Handler when click button

Hello.

I developed a Screen with touchgfx with a ModalWindow with button and BoxWithBorder

I add interaction on this button that calls virtual function.

When I press the button the processor goes to HardFault.

Can some one help me ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
