This is because you have not started the LFCLK

add this below code in your main() function

        buttons_init();
        

        err_code = nrf_drv_clock_init();
        APP_ERROR_CHECK(err_code);

        nrf_drv_clock_lfclk_request(NULL);
        
        bsp_buttons_enable();
    
        bsp_event_to_button_action_assign(0, 1, BSP_EVENT_KEY_0);
        bsp_event_to_button_action_assign(1, 1, BSP_EVENT_KEY_1);
