Error in initializing ST-LINK device. Reason: Target not halted.

Hello everyone, 

I recently bought the NUCLEO-N657X0-Q and I am trying to debug it using the ST-LINK_gdbserver.

Also this is my first development board and I don't know where to look. The data sheet and reference manual give me nothing in this regard and I am helpless. 

Here is the command line output:

$ /opt/ST/STM32CubeCLT_1.20.0/STLink-gdb-server/bin/ST-LINK_gdbserver --swd \ 
 -cp /opt/ST/STM32CubeCLT_1.20.0/STM32CubeProgrammer/bin -v -l 31 --frequency 8000 -k

Error in initializing ST-LINK device.
Reason: Target not halted.

I am on macOS Tahoe 26.2.

I have ruled out that it is due to connectivity problems because I can program the board and run software on it using the STM32CubeProgrammer and its corresponding STM32_Programmer_CLI. I can also halt the core, inspect memory, read system registers and configure peripherals. I have also not encountered anyone with a similar problem on the internet.  BOOT0 is LOW and BOOT1 is HIGH to enter development boot. The board is connected through the CN10 USB-C port and the 5V_PWR LED (LD1) is ON. Also the PWR status tricolor LED (LD4) is GREEN which indicates that the power delivery is okay.

 I got a simple blinking LED to work with basic GPIO but more complex projects require a debugger. I am deliberately avoiding the STM32CubeIDE because I do not want any hardware abstractions, but even CLion throws this exact error when I try to connect.

Please help me resolve this issue, I would be grateful!

For certainty here are more details from the STM32_Programmer_CLI:
