im using STM32F103C8T6 , Im using it without any problem but yesterday i upload code , the code is not correct then i make some changes and upload again then it showing this error i use both ST-LINK UTILITY and STM32CubeProgrammer , i follow some solution in this website but is not working for me . look forwad for your reply thank you

What board is that? - give a link

and what ST-Link are you using - genuine, or a clone ?

The errors messages show that your PC is communicating with the ST-Link, but the ST-Link cannot communicate with the target microcontroller.

So what, exactly, did you change?

Have you disabled the pins used by the SWD connection?

Hello @mubarak,

'X' -pill flavor boards (black, blue ) are not efficient and suffer from fake MCU. So I'm afraid, something related to the MCU itself.

I recommend you to use one of ST boards having genuine MCUs: NUCLEO-F103RB

Again: is that genuine, or a clone ?

As I stated before, I recommend to use genuine products from ST.

Many users on this community are suffering from fake chips on these boards.

Indeed.

@mubarak Both the boards, and the clone ST-Links - See:
