SDL2 Program Crashes After Generating Random Pixels for a Few Seconds

I am working on a project using SDL2 to generate random pixels in a terminal display.

My program compiles and runs:

#include <SDL2/SDL.h>
#include <random>

int main(int argc, char* argv[]) {
    if (SDL_Init(SDL_INIT_VIDEO) != 0) {
        return 1;
    }
    SDL_Window* window = nullptr;
    SDL_Renderer* renderer = nullptr;

    if (SDL_CreateWindowAndRenderer(2000, 2000, 0, &window, &renderer) != 0) {
        SDL_Quit();
        return 1;
    }
    SDL_RenderSetScale(renderer, 20, 20);

    int x{25};
    int y{25};

    std::random_device dev;
    std::uniform_int_distribution<uint8_t> nd(0, 3);

    while (true) {
        uint8_t dir = nd(dev);
        Uint8 r, g, b;

        switch (dir) {
            case 0:
                x -= 1;
                y -= 1;
                r = 245;
                g = 169;
                b = 184;
                break;
            case 1:
                x += 1;
                y -= 1;
                r = 91;
                g = 206;
                b = 250;
                break;
            case 2:
                x -= 1;
                y += 1;
                r = 255;
                g = 255;
                b = 255;
                break;
            case 3:
                x += 1;
                y += 1;
                r = 0;
                g = 0;
                b = 0;
                break;
        }

        SDL_SetRenderDrawColor(renderer, r, g, b, 255);
        SDL_RenderDrawPoint(renderer, x, y);
        SDL_RenderPresent(renderer);

        if (x > 50 || x < 0 || y > 50 || y < 0) {
            x = 25;
            y = 25;
        }

        
    }

    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}

...but it crashes after generating random pixels for about 2 seconds.

Any help or leads?

I am using MSYS with a C++20 compiler.

Sorta fixed it after using the comments:

#include <SDL2/SDL.h>
#include <random>

    if (SDL_Init(SDL_INIT_VIDEO) != 0) {
        return 1;
    }

    SDL_Window* window = nullptr;
    SDL_Renderer* renderer = nullptr;

    if (SDL_CreateWindowAndRenderer(2000, 2000, 0, &window, &renderer) != 0) {
        SDL_Quit();
        return 1;
    }

    SDL_RenderSetScale(renderer, 20, 20);

    int x{25};
    int y{25};

    std::random_device dev;
    std::uniform_int_distribution<uint8_t> nd(0, 3);

    bool running = true;
    while (running) {
        SDL_Event event;
        while (SDL_PollEvent(&event)) {
            if (event.type == SDL_QUIT) {
                running = false;
            }
        }

        uint8_t dir = nd(dev);
        Uint8 r, g, b;

        switch (dir) {
            case 0:
                x -= 1;

                break;
            case 1:

                break;
            case 2:

                r = 255;
                g = 255;
                b = 255;
                break;
            case 3:
                x += 1;
                y += 1;
                r = 0;
                g = 0;
                b = 0;
                break;
        }

        if (x >= 0 && x <= 50 && y >= 0 && y <= 50) {
            SDL_SetRenderDrawColor(renderer, r, g, b, 255);
            SDL_RenderDrawPoint(renderer, x, y);
            SDL_RenderPresent(renderer);
        }

        if (x > 50 || x < 0 || y > 50 || y < 0) {
            x = 25;
            y = 25;
        }
    }

    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}

tysm for the help , problem solved :)
