Good day,
I'm pretty new with stm32 microcontrollers and I have some trouble, so I would like to ask you for help.

Yesterday I downloaded Visual Studio and VisualGDB for programming. Everything worked fine, I uploaded few times test application with blinking LED. After that I tried to test button. I didn't find any tutorials so I tried to write something by myself (Now, I think that was a stupid idea). I wrote something like this:
#include <stm32f4xx_hal.h>
#ifdef __cplusplus
extern "C"
void SysTick_Handler(void)
int main(void)
    __GPIOA_CLK_ENABLE();//Clock for LED
    __GPIOC_CLK_ENABLE();//Clock for Button
    GPIO_InitTypeDef GPIO_InitStructure;
    GPIO_InitStructure.Pin = GPIO_PIN_5;//LED pin
    GPIO_InitStructure.Pin = GPIO_PIN_13;//Button pin
    GPIO_InitStructure.Mode = GPIO_MODE_OUTPUT_PP;
    GPIO_InitStructure.Speed = GPIO_SPEED_HIGH;
    GPIO_InitStructure.Pull = GPIO_NOPULL;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStructure);
    GPIO_InitStructure.Mode = GPIO_MODE_INPUT;
    GPIO_InitStructure.Speed = GPIO_SPEED_HIGH;
    GPIO_InitStructure.Pull = GPIO_NOPULL;
    HAL_GPIO_Init(GPIOC, &GPIO_InitStructure);
    for (;;)
        if (HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_13)){
            HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_SET);
 Microcontroller successfully uploaded program, but it didn't work like I expected.
After this I tried to get back to LED blinking but I got this error:


Did I killed STM32F411 or this is something fixable?

Thank you.
