ST Link not recognizing STM Cube Programmer? - From screenshot you can see pulls up single character serial number and has no target information. I can (and did) upgrade firmware to latest on ST Link. Downloaded all drivers etc. Still won't connect. Keep getting "UR connection mode is defined with the HWrst reset mode" log entry.

@SBenn.2 The serial number on your screenshot is not 1-character. ???

Yes that's right, I only included the screen shot after the SHARED option is ticked, without being ticked the fake ST-Link is not detected in any way in CubeIDE i.e. not even showing the ! character, this is where it is different from CubeProgrammer, which does show an ! as the serial number, if not shared.

I had the same problem. Instead of the serial number, "C" was displayed. In the cube programmer I set the "Shared" option to Enable and everything worked.
