Suggests the MCU is non-responsive.
Did you program it previously?
Does it work with STM32 Cube Programmer as a stand-alone application?
If you have the LDO/SMPS settings wrong you can block access to the STM32.
The trick then is to solder a jumper between BOOT0 (BT0) and VDD.
With BOOT0 HIGH remove ALL power and USB
Reapply power/connections.
Attempt to access via STM32 Cube Programmer.
If that succeeds, ERASE your code from the part.
Fix your code.

Hey Clive, should the board use copper pads for tweezer boot short to bootloader, or slide switch for a more permanent solution? Say user developping his own bootloader or other possible cases?

After having to do this more than once, I find the following to be a workable solution, along with the spare jumper(s) ST conveniently parked on the back of the board. People should do whatever works for them..
