STM32 G071 full erasing problem

[Afsal]

I am uploading a custom bootloader to an STM32G071. When I select Full Erase, I get the error "Error occurred during mass erase." How can I solve this? I am using Utility.

G0 series is probably to new for ST-LINK Utility. Try STM32CubeProg | Software - STMicroelectronics instead.
