Welcome @MROWL, to the community!

Can you please post a photo of the ST link?

If it is not an original ST-LINK like e.g. the famous ST-LINK/V2 or the race-car fast ST-LINK/V3 from STMicroelectronics, you will not be successful, because these small, colourful, illegally copied and very cheap tin cans are not supported by the official software. When you try to upgrade their firmware, they do not show a serial number, nor can the upgrade be completed.

In addition, even with an original ST-LINK you should not be surprised if something does not work with the Blue Pill, because for a long time only (illegal) counterfeits of the STM32F103 have been installed there.

My tip: buy original hardware, such as a NUCLEO board, because you are safe from surprises and will have a lot of success.

or you have accidentally selected the use of serial number xxx only - try uncheck st-Link S/N !

in debug configuration:

+

to program the bluepill, if your (old) stlinkV2 dont work, you can use the onboard stlink on your nucleo board ;

set jumpers ...to use stlink extern, connect gnd/swd/swc to bluepil + flash it .
