Hello @Anurag and welcome to the ST Community 😊.

Could you check another USB port and try using a USB data cable not just a charging cable.

Best Regards.

From error message "No device found on target" -> st-link cannot find target cpu G031 .

So use stm32CubeProgrammer , connect : under reset - and show screen, what it telling.

Maybe you have to erase it first or set flash to not protected sate.

But be careful, setting the option bytes wrong, you can "kill" the cpu , you can no more access it then !

Read in rm first about option bytes, so you know, what you do !!
