Unplugged target or STLink already in use or STLink USB driver not installed. System32 Workbench

Hi,

I am using STM32 Workbench with NUCLEO-H743ZI. The IDE is unable to connect to the board. I get the message Unplugged target or STLink already in use or STLink USB driver not installed. I have installed dpinst_amd64 from en.stsw-link009 and have tried different boards with different USB cables. I am running Windows 10.

How can I get the System32 workbench IDE to connect to the NUCLEO-H743ZI?

Here is the OpenOCD error details:
