StmCubeIDE Issues with debugging STM32F411CEU6

Question

I have ordered the black pill ( STM32F411CEU6, real ones ) to replace my blue pill dev kits that didn't have enough RAM and have had nothing but issues getting it going. I have generated the project using STM32CubeIDE.

I'm using A11, 12, 13 for GPIO output and PB9, 8 for I2C communication, and A10, 11 for my USART device.

I am able to get the st link programmer and software to detect my black pill and debug for a short duration until I enter MX_GPIO_Init()

After this the programmer loses communication with the device and prevents me from doing any real programming. Some places I have looked says to try to set the Sys -> Debug setting to "Serial Wire" but this is disabled by default for me and am unable to switch it.

In context of debugging when I do debug in live mode I can see a debug enabled

Starting server with the following options:
        Persistent Mode            : Disabled
        Logging Level              : 1
        Listen Port Number         : 61234
        Status Refresh Delay       : 15s
        Verbose Mode               : Disabled
        SWD Debug                  : Enabled
        InitWhile                  : Enabled

So the debugging looks like it's set up properly but I just don't understand why it can't call the init for the GPIO from looking at the debug console I get this

handle_vCont_c, Failed continue thread

which is thrown after entering this function

HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

which doesn't make a whole lot of sense to me as I have not seen this before, can someone please help me out setting up this project properly? thanks.

The serial wire debug interface is defined for PA13 and PA14. In CubeMx IDE, first set SYS->Debug->Serial Wire. Select another pin for GPIO instead of PA13.
