"Failed to list debug probes" when scanning for ST-LINK S/N

[Lachie]

STM32 Cube IDE throws failure message "Failed to list debug probes" when scanning for ST-LINK S/N under Debug Configurations/Debugger/GDB Server Command Line Options/Interface.

Problem has presented itself in last hour. It was working with a Nucleo-F042K6 and now not working with either the Nucelo-F042K6 and a Nucleo-F746ZG.

Trying to debug code that incorporates FreeRTOS Middleware utilising CMSIS_V2 hence the move to the significantly more powerful Nucleo-F746ZG as I realised RTOS is not compatible with the Nucelo-F042K6.

Ran ST-LINK Upgrade successfully on both boards.

Code compiled and downloaded from online mbed compiler works so I expect it is not an issue with the board.

Any assitance would be greatly appreciated.

Problem found to be Avast Antivirus, uninstalling STM32 Cube IDE and Avast and then reinstalling STM32 Cube IDE fixed the problem.
