Run target on STM32H747I-DISCO failed

Any demo would display the same error...

I use on another PC with cubeprogrammer 2.6.0, here is different error.

previous error using another PC with cubeprogrammer 2.5.0 seems to be ok now.

@victagayun​  I am also having exactly same problem when trying with STM32CubeProgrammer V2.6.0 on STM32H747i-Disco board. Can someone please provide any solution.
