STM cube programmer v2.20 freezes board whereas v2.17 doesn't

[Luke-r4]

I am flashing a hex file that has power management that enables the low power stop modes. On version 2.17 everything works fine, but when I upgrade to version 2.20 it starts to freeze when the board goes into sleep mode. 

I have been flashing using the CLI.

I have tried multiple times on v2.20 and when I downgrade back to v2.17, it starts working again.

I know that it works on v2.15 as well.

I am using the exact same hex file each time.

Download the contents of the flash and compare them. The chip doesn't know what version of software was used to flash it. If the flash is the same, behavior should be the same.

Hello, 

thanks for your response. I edited the post to clarify that I'm using the same hex file each time and that its freezing once the board goes into sleep mode. Does this change anything in your reply?

Thanks
