Hi. is any one facing issue like mine.  After updating STM32CUBEPROGRAMMER TO V2.20 external loader giving error at erasing external memory. when i download the code in controller having external qspi flash, it is showing error "failed to erase chip".  screenshot is attached. If i perform Full CHIP Erase. I am able to erase the chip. ever single sector is erased. but my code uses 111 sectors of external memory which is failing to ease. same issue is giving at cubeide 1.19.0. before updating everything was working. i upadated IDE and it failed to erase the chip. but my old cube programmer was doing job. when i updated cube programmer, it also stopped erasing external memory 111 sectors.
