ST-Link won't fully bootload successfully

A few months ago I made a post regarding a PCB I designed (see post here: https://www.reddit.com/r/PrintedCircuitBoard/comments/1b3wilu/pcb_design_review_request_mq2_gas_sensor/) where I used the STM32F030F4P6 MCU. I planned on boot loading this MCU with the ST-LINK/V2 : https://www.digikey.com/en/products/detail/stmicroelectronics/ST-LINK-V2/2214535 ,

6 pin tag connect: https://www.tag-connect.com/product/tc2030-idc-nl and the adaptor for the ST-LINK/V2: https://www.tag-connect.com/product/tc2030-idc-nl

The boatload seems to run successfully by identifying the MCU and saying the file download is complete, but the LED seems to still be flashing orange as if it's trying to complete the upload. I can upload code to the board with the tag connect, although nothing happens after finishing the upload. For reference, I am first writing a simple blink-on blink-off LED program, and the LED doesn't blink (I checked the LED with a multimeter on the board and it does light up so it's not a hardware issue.

Here is the output from the console terminal:

Any help is greatly appreciated.

Says it downloaded and verified the code is on the device..

Now you'll need to debug it and step through your code to understand what is and is not happening.

Perhaps instrument Error_Handler() and HardFault_Handler() so you'll know if they got there rather than die silently in a while(1) loop

What LED is orange? Your LED or the one on the ST-LINK? Is the ST-LINK just probing/observing connectivity after programming?

Did you set STM32 Cube Programmer to auto-run the code? Are you doing this from STM32 Cube Programmer or the IDE/Debugger? If in the debugger, STOP the code and see where it is stuck. Did it reach you LED blinking code?

>>ST-Link won't fully bootload successfully

I'm not entirely clear WHAT this means.

The software says it's done.

Your code is on the device.

Disconnect and press reset, and the MCU should attempt to run your code. It may not be successful for a myriad of reasons.

>>STM32CubeProgrammer v2.12.0

That's a bit antiquated, at v2.16 now. Use current tools where possible so old issues don't need to be re-litigated.

Sorry, what I meant was the STM32 Cube IDE claims that the bootloader is done, but the LED on the STLINK V2 still blinks green and red back and forth despite saying the program is finished. Pressing the resume button after bootloader doesn't seem to do have the code run successfully, and the LED on the STLINK still flashes between red and green. As for the code, right now I just want to blink an on board test LED, the code is as follows:

#include "main.h"
#define led0 GPIO_PIN_7


int main(void)

 MX_GPIO_Init();

	 HAL_Delay(250);
	 HAL_GPIO_WritePin(GPIOA,led0,GPIO_PIN_RESET);
	 HAL_Delay(250);
 }

The code can fully upload but the LED on my board doesn't blink. I have D27 tied to PA7, making GPIO pin 7 and port A with GPIO_PIN. Every time I upload the code it says the project requires code generation, and it successfully uploads but the LED doesn't blink nor do I see a signal on my scope. I checked the 6 programming pins and they all seem to be operating as expected, tried also holding down the reset switch while uploading although this seemed to stop the boatload or program from uploading successfully.
