What does the error message actually say? Target Not Found?

Did you get the LDO/SMPS settings wrong?

Try power cycling the board with BOOT0 HIGH, see if it will connect, and then erase the broken user code.​

Yes, the real error is "Target not found". I am trying to try the way you suggested. Thank you.
