STM32MP257F-DK - Target is not responding, retrying. Debugger connects and disconnects.
I just recently unboxed and connected up my STM32MP257F-DK and am trying to follow a simple blink LED project. (https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step2_Blink_LED).
My boot pins are 0011 (in Development Mode) since I don't want to boot up in Linux, just work with the M33 Core. My LEDs when I connect up my board to my computer are: LD11 is solid green, LD5 is solid red, KD6 is solid green, and LD7 is solid red.
I've been having issues with the debugger and flashing. My project builds fine with no warnings or errors but when I run with debugger I get this on my Console:

I've configured my debugger to this (connect under reset) and made some progress where my Debugger started connecting but then disconnecting (see above logs) whereas before it was never connecting:
I don't have OpenOCD installed not sure if I should be using that as my debug probe instead.
When I go into my CubeProgrammer, and try to connect:
And then go to Debug Authentication to 'Discover' I get:
I've been trying to follow these steps: https://community.st.com/t5/stm32-mcus/how-to-solve-debugger-connection-issues/ta-p/49693 but, I'm pretty lost at this moment and would appreciate any help! I also haven't tried much in CubeMX since I'm not sure how to config the debug pins for the STM32MP257F-DK.
