"Could not verify ST device" when Debugging with RTOS Proxy

Hi,

 

I’m working on an STM32H7S78‑DK project that uses FreeRTOS, with STM32CubeIDE v2.0.0 on Windows. The ST‑LINK debugger works normally as long as RTOS Proxy is disabled, but cannot be launched once I enable RTOS Proxy. Error message and Console prints as below:

My debugger configuration:

The exact same project used to run fine with RTOS Proxy enabled, but it suddenly started failing one day without any changes to my debug settings. The board itself should be good, as it works normally on another development setup.

Has anyone seen this issue before, or is there any known limitation with RTOS Proxy on the H7S series? Any pointers would be appreciated.
