SDL remembers last instance"s user input

I am working on an SDL project in C and I am having trouble with the input handling.

whenever I start my SDL app it remembers the last app's inputted keys and SDL_PollEvent always gives repeatedly the last key that was pressed in the previous instance of the program.

btw I am compiling the code in a WSL window I have tried the same piece of code in a visual studio environment and it worked perfectly fine. So can someone explain what's happening?

Here is the sample code:

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

int main() {
    SDL_Event event;

    SDL_Window* sdlwind;
    if(SDL_Init(SDL_INIT_VIDEO) != 0) {
        fprintf(stderr, "SDL_Init Error : %s", SDL_GetError());
        return 1;
    }
    sdlwind = SDL_CreateWindow("Engine", 0, 0, 1080, 840, SDL_WINDOW_SHOWN);

    if(!sdlwind) {
        fprintf(stderr, "SDL_CreateWindow Error : %s", SDL_GetError());
        return 1;
    }

    printf("Start");
    while (1)
    {
        while (SDL_PollEvent(&event))
        {
            printf("%c\n", event.key.keysym.sym);
        }

        if(event.key.keysym.sym == SDLK_a) {
            break;
        }
    }
    
    SDL_DestroyWindow(sdlwind);
    SDL_Quit();
    
    return 0;
}

This sample code has outputted the first time:

OUTPUT
,
,
,
,
,
,
// etc since the last key pressed in the previous instance was , and after terminating the program by pressing a
// the next output becomes
OUTPUT
a
a
a
a
a
// etc

I have tried removing the executable and launching another SDL program but the same problem persists. I have later tried to take input normally with getchar() but it didn't register any key so I am not sure but it might not be a problem related to the stdin it must be smthng with SDL and WSL.
